VN9004AJTR

Power Distribution Switches, Load Drivers Overview

The VN9004AJTR is a single-channel high-side driver manufactured using ST VIPower M0-9 technology in a PowerSSO-16 package. It drives 12 V automotive grounded loads via 3 V and 5 V CMOS-compatible interfaces. The device provides protection and diagnostics, including load current limitation, overload active management by power limitation, and overtemperature shutdown with configurable latch-off. A FaultRST pin unlatches the output or disables latch-off. A multifunction multiplexed analog output pin delivers high-precision proportional load current sense, supply voltage feedback, chip temperature sense, and detection of overload, short circuit to ground, short to VCC, and OFF-state open-load.
