PRODUCTION DATA
The device enters UVLO if the L+ voltage falls below V(UVLO). (For the device without the integrated LDO, the device monitors VCC_IN in addition to L+. UVLO happens if either supply falls below the threshold.)
As soon as the supply falls below V(UVLO), NFAULT is pulled low, and the driver (CQ) is disabled (Hi-Z). Receiver performance is not specified in this mode.
When the supply rises above V(UVLO), NFAULT returns to Hi-Z (given no other fault conditions present). The CQ output is turned on after t(UVLO) delay.
