Application Information and Additional Details

State Diagram

UVLO/Sleep Mode

The IC remains in the UVLO condition until the voltage on the VCC pin exceeds the VCC turn on threshold voltage, VCC

. During the time the IC remains in the UVLO state, the gate drive circuit is inactive and the IC draws a quiescent

current of ICC START. The UVLO mode is accessible from any other state of operation whenever the IC supply voltage

condition of VCC < VCC UVLO occurs.

The sleep mode is initiated by pulling the EN pin below 2.5V (typ). In this mode the IC is essentially shut down and

draws a very low quiescent supply current.

Normal Mode

The IC enters in normal operating mode once the UVLO voltage has been exceeded. At this point the gate driver is

operating and the IC will draw a maximum of ICC from the supply voltage source.
