PRODUCTION DATA
VCC1 supports an input range of 3V to 5.5V in order to support both 3.3V and 5V controller signaling. VCC1 is monitored with both an undervoltage and overvoltage comparator circuit to ensure valid operation. UV and OV conditions of VCC1 are recorded in STATUS2[UVLO1_FAULT] and STATUS2[OVLO_FAULT1], respectively(STATUS2). See the Undervoltage Lockout (UVLO) and Overvoltage Lockout (OVLO) section for more specifics regarding the OV and UV functions.
