High-side and low-side switches are widely used in automobiles, such as for controlling headlights, airbag activation, and relay control. A semiconductor switch configured on the upper circuit is called a high-side switch, while one configured on the lower circuit is called a low-side switch.Today, we recommend a domestic intelligent low-side switch,which can completely replace Infineon’sBSP75N.
1. Overview
A single-channel intelligent low-side power switch, suitable for various resistive and inductive loads in automotive and industrial applications, such as relays and solenoids. It also integrates multiple protection features: over-voltage protection, current limiting, over-temperature protection, short-circuit protection, etc.
2. Key Performance
1. Complies with AEC-Q100 certification standards
2. Drain-source voltage: 60V
3. Clamping energy: 400mJ
4. On-resistance: 550 mΩ (Tj=25°C)
5. Load current: 0.7A
6. Off-load protection voltage: 80V
7. Power dissipation: 1.8W
8. Operating junction temperature: -40°C to 150°C
9. Package: SOT-223
3. Application Scenarios
1. Compatible with 12V/24V DC power switch applications and 42V power networks
2. Suitable for resistive, capacitive, and inductive loads
3. Replaces mechanical switches, fuses, and discrete circuits
