Application Information and Additional Details
UVLO Mode:
The IC is in the UVLO mode when the VCC pin voltage is below VCCUVLO. The UVLO mode is accessible fro
any other state of operation. In the UVLO state, most of the internal circuitry is unbiased and the IC draws
quiescent current of ICCSTART.
The IC remains in the UVLO condition until the voltage on the VCC pin exceeds the VCC turn on thresh
voltage, VCC ON.
Normal Mode:
The IC enters in normal operating mode once the UVLO voltage has been exceeded. At this point the gate drive
are operating and the IC will draw a maximum of ICC from the supply voltage source.
