SNVSBA5C December 2019 – May 2024 LP8866-Q1
PRODUCTION DATA
If during LP8866-Q1 device operation voltage of CPUMP pin falls below typical 4.2V, boost, power-line FET, and LED outputs are turned off, and the device enters Fault Recovery mode and then attempt to restart 100ms after fault occurs. The CP_STATUS fault bit will beset in the SUPPLY_FAULT_STATUS register, and the INT pin are triggered.
If during LP8866-Q1 device initialization, the charge pump fly capacitor is disconnected or shorted, charge pump are turned off. In result, boost, power-line FET, and LED outputs are turned off, and the device enters Fault Recovery mode and then attempt to restart 100 ms after fault occurs. Both CPCAP_STATUS and CP_STATUS fault bits are set in the SUPPLY_FAULT_STATUS register, and the INT pin are triggered.
