Identifying Popular Chip Part Numbers from TI, NXP, ON, and Infineon

After the large-scale chip shortage has come to a close, friends in the chip market have been somewhat affected by the wave of order cancellations, with the biggest change being less overtime. Previously, when there were orders, they would work overtime for testing (to verify the authenticity of chips), but now without orders, they are busy developing new solutions.

However, new orders are poised to surge, with various automotive subsidies being issued across the country, and China’s new energy vehicles leading the way internationally. The gap in automotive chips cannot keep up with the demand for various automotive-grade chips, leading to high market prices. This issue has resulted in many popular automotive and industrial control chips emerging, which are in high demand due to long lead times from manufacturers and the difficulty of domestic replacements. Below are ten popular chips we have selected from the past month (model numbers):

1. The new chip “Assassin” “AUIRS1170STR”

2. The city is deep, urgently seeking a 5 yuan ticket home “TPS51200DRCR”

3. The leader in in-car entertainment “MCIMX6U7C”

4. Heat and price soar together “VNQ7050AJTR “

5. The automotive chip that earns effortlessly “TPS7B7702”

6. The automotive chip that earns effortlessly “TPS7A6650”

7. Gently waking the sleeping soul “KSZ9031RNXIA”

8. The comeback of the hotcake “NCP45520IMNTWG-H”

9. Who has my expensive request to surpass “MK64FN1M0VLQ12”

10. Engraving “low power consumption” into the bones “NRF52832-QFAA-R”

NO.1 The New Chip “Assassin”

AUIRS1170STR: Risen to 200-300

AUIRS1170STR was priced around 19 yuan last December, with a normal price possibly only 8-9 yuan. Now, according to observations from friends in the market, this chip has currently risen to 200-300, which is about 30 times the normal price.

AUIRS1170STR is Infineon’s power device – automotive-grade smart secondary side driver IC, used in automotive DC-DC converters, automotive SMPS, and high-power industrial SMPS.

Infineon’s shortage has gone from a large-scale shortage to a small-scale shortage, with the most critical still being automotive materials.

NO.2 The city is deep,

Urgently seeking a 5 yuan ticket home

TPS51200DRCR: Normal price

“At that time, the price was high, and it was called to seventy or eighty yuan in the market. Later, it dropped sharply, and it is estimated that there were not many transactions.”

TPS51200DRCR’s normal price is below 5 yuan. Since last April, the price has risen to over 60+, and since September, it has dropped sharply and stabilized at over 2 yuan, which is close to the normal price (a few dimes in RMB).

TPS51200DRCR is a power management IC specifically for DDR memory, used for DDR, DDR2, DDR3, DDR3L, low-power DDR3, and DDR4 memory terminal voltage regulators, notebooks, desktops, servers, telecommunications and data communication, copiers, and printers.

The consumer electronics market has reached a bottleneck, and destocking has been reflected from downstream products to upstream chips. The prices of general-purpose analog chips in the spot market have gradually returned to normal. It is worth noting that TPS51200DRCR is used in DDR memory, and currently, the market demand for memory chips is also weak, and the price reduction trend is obvious.

NO.3 The leader in in-car entertainment

MCIMX6U7CVM08AD:

Price fluctuating upwards

The official price of MCIMX6U7CVM08AD is 27.48 USD (approximately 185 RMB). It is said that this chip was priced over 400 yuan at the beginning of June, and now it has risen to over 800 yuan.

MCIMX6U7CVM08AD is NXP’s i.MX 6 series 32-bit MPU, used in automotive, industrial control, mobile consumer electronics, smart home, etc. The i.MX 6 series application processors combine scalable platforms with a wide range of integration and high energy efficiency, making them particularly suitable for multimedia applications.

It is rumored that NXP will increase prices by about 15% across the board starting July 1, and currently, the shortage of some automotive and industrial parts remains prominent.

NO.4 Heat and price soar together

VNQ7050AJTR: Soaring since this year

The popularity of VNQ7050AJTR has significantly soared since this year, and the price has also soared, from around 7 yuan’s normal price to about 500 yuan now.

This is an ST automotive smart power IC – a four-channel high-side driver chip, used for all types of automotive resistive, inductive, and capacitive loads or specifically for automotive signal lights.

ST currently has a shortage concentrated in discrete devices, automotive MCUs, power switches, etc.

NO.5 The automotive chip that earns effortlessly

TPS7B7702QPWPRQ1:

Second wave of price increases this year

Recently, the search volume for TI automotive materials has been quite high, with TPS7B7702QPWPRQ1 rising from around 7 yuan’s normal price to over 100 yuan. After dropping from 800 yuan to over 200 yuan last quarter, it has now risen to around 600 yuan.

TPS7B7702QPWPRQ1 is TI’s automotive dual-channel adjustable low-dropout regulator, used in infotainment systems, active antenna power supplies, surround camera power supplies, and high-side power switches for low current applications. It belongs to the TPS7B770x-Q1 series, which includes single-channel 7701 and dual-channel 7702.

Prices keep rising, and the “long-distance runners” may have started to reap their rewards.

NO.6 The automotive chip that earns effortlessly

TPS7A6650QDGNRQ1:

Still at a high price

The popularity of TPS7A6650QDGNRQ1 is among the top positions on multiple platforms across the web, with a normal price of about 1.7 yuan, currently around 280 yuan, which is a significant drop from over 400 yuan last month, but still at a high price.

TPS7A6650QDGNRQ1 is a TI automotive low-dropout regulator with power good indication function (150mA, battery-powered operation at 40V, low IQ). It is used in infotainment systems with sleep mode, body control modules, and standard always-on battery.

TI’s specialized analog chip prices are unlikely to drop to normal prices in the short term, and there may even be fluctuating price increases, mainly due to strong demand in specialized fields such as automotive.

NO.7 Gently waking the sleeping soul

KSZ9031RNXIA: Rebounding

KSZ9031RNXIA’s normal price is 20 yuan, and after the last price fluctuation, it has refreshed its high record this month, rising from around 200 yuan in May to about 1500 yuan.

Microchip’s KSZ9031 is an Ethernet chip, used not only in automotive networks but also widely in laser/network printers, broadband gateways, gigabit SOHO/SMB routers, network TVs, gaming consoles, industrial control, etc.

NO.8 The comeback of the hotcake

NCP45520IMNTWG-H:

300 times the normal price

The official guide price for NCP45520IMNTWG-H is about 3.2 yuan. Since the beginning of this year, it has soared, currently priced around 1000 yuan, which is over 300 times the normal price.

This is a power management chip (load switch), belonging to ON Semiconductor’s NCP455XX series, widely used in portable electronic devices and systems, telecommunications, networking, medical and industrial equipment, set-top boxes, residential gateways, handheld devices, laptops, and tablets.
