UVLO/Sleep Mode
The IC remains in the UVLO condition until the voltage on the VCC pin exceeds the VCC turn on threshold voltage, V CC
ON . During the time the IC remains in the UVLO state, the gate drive circuit is inactive and the IC draws a quiescent
current of I CC START . The UVLO mode is accessible from any other state of operation whenever the IC supply voltage
condition of VCC < V CC UVLO occurs.
The sleep mode is initiated by pulling the EN pin below 1.6V (typ). In this mode the IC is essentially shut down and draws
a very low quiescent supply current.
Normal Mode and Synchronized Enable Function
The IC enters in normal operating mode once the UVLO voltage has been exceeded and the EN voltage is above V ENHI
threshold. When the IC enters the Normal Mode from the UVLO Mode, the GATE output is disabled (stays low) until V DS
exceeds V TH3 to activate the gate. This ensures that the GATE output is not enabled in the middle of a switching cycle.
This logic prevents any reverse currents across the device due to the minimum on time function in the IC. The gate will
continuously drive the SR MOSFET after this one-time activation. The Cycle by Cycle MOT protection circuit is enabled in
Normal Mode.
MOT Protection Mode
If the secondary current conduction time is shorter than the MOT (Minimum On Time) setting, the next driver output is
disabled. This function can avoid reverse current that occurs when the system works at very low duty-cycles or at very
light/no load conditions and reduce system standby power consumption by disabling GATE outputs. The Cycle by Cycle
MOT Check circuit is always activated under Normal Mode and MOT Protection Mode, so that the IC can automatically
resume normal operation once the load increases to a level and the secondary current conduction time is longer than
MOT.
