PRODUCTION DATA
The TPS9238x device supports VIN undervoltage protection. The VIN undervoltage falling threshold is 3.85-V typical and rising threshold is 4-V typical. If during operation of the TPS9238x device, the VIN pin voltage falls below the VIN undervoltage falling threshold, the boost, LED outputs, and power-line FET will be turned off, and the device will enter FAULT RECOVERY mode. The FAULT pin will be pulled low. The TPS9238x will exit FAULT RECOVERY mode after 100 ms and try the start-up sequence again. VIN_UVLO fault detection is available in SOFT START, BOOST START, and NORMAL state.
