Key Features
- MultiSense Diagnostic Functions: Provides multiplexed analog feedback of load current, VCC supply voltage, and chip temperature. It also includes overload and short to ground indication, thermal shutdown indication, OFF-state open-load detection, and output short to VCC detection.
- Advanced Protections: Includes undervoltage shutdown, overvoltage clamp, load current limitation, self-limiting of fast thermal transients, and configurable latch-off on overtemperature or power limitation with a dedicated fault reset pin.
- Low Standby Current: Very low standby current to minimize power consumption.
- Compatibility: Compatible with 3 V and 5 V CMOS outputs.
- Fault Reset: A FaultRST pin to unlatch the output in case of a fault or to disable the latch-off functionality.
