Two Channel High-Side Switch with Current Sensing

This automotive-grade two-channel high-side switch provides a robust power management solution by integrating overcurrent, thermal, and open-load protections alongside a dedicated current-sensing function for real-time load monitoring.

This is a two Channel high-side switch designed for automotive applications. It has a built-in overcurrent limit function, thermal shutdown protection function, open load detection function, low power output-OFF function etc. It also has a current sensing function of output load current.

Resistor R1, R2, R6, R7 limit resistance for the negative surge
Resistor R3, R8, capacitor C2, C4 for noise suppression filters
