ZHCSKL3B December 2019 – October 2020 LP8866-Q1
PRODUCTION DATA
The LP8866-Q1 device supports VIN undervoltage and overvoltage protection. The undervoltage threshold is programmable through external resistor divider on UVLO pin. If during operation of the LP8866-Q1 device, the UVLO pin voltage falls below the UVLO falling level (0.787 V typical), the boost, LED outputs, and power-line FET will be turned off, and the device will enter STANDBY mode. The VINUVLO_STATUS bit is also set in the SUPPLY_FAULT_STATUS register, and the INT pin is triggered. When the UVLO voltage rises above the rising threshold level the LP8866-Q1 exits STANDBY and begins the start-up sequence.
