ZHCSLM3B August 2020 – May 2024 LP8864-Q1
PRODUCTION DATA
During device initialization, any of un-used LED outputs pins are checked whether connected to GND or not. If they are not connected to GND as expected, the LP8864-Q1 reports invalid string fault and tries to function normally if possible. The INVSTRING_STATUS fault bit is set in the LED_FAULT_STATUS register, and the INT pin is triggered. The LEDSET resistor missing or invalid fault is not detected after initialization, so that the LP8864-Q1 operates in the configuration determined during initialization even though the LEDSET resistor is missing or invalid after initialization.
