SYNC
HYST
SCOMP
External-Clock Sync Input. Connect SYNC to AGND when not using an external clock.
Hysteresis Input
Slope-Compensation Capacitor Connection

DT
Dead-Time Resistor Connection. Connect a resistor from DT to AGND to program the
output dead time. Connect to REG5 for NDRVA and NDRVB maximum 50% duty cycle.

UVLO/EN
Externally Programmable Undervoltage Lockout. UVLO/EN programs the input start
voltage. Connect UVLO/EN to AGND to disable the output.

FLTINT
Fault-Integration Input. A capacitor connected to FLTINT charges with an internal 60μA
current source during persistent current-limit faults. Switching terminates when V
FLTINT
is
2.8V. An external resistor connected in parallel discharges the capacitor. Switching
resumes when V
FLTINT
drops to 1.6V.

Current-Sense Resistor Connection
Analog Ground. Connect to PGND.
Power Ground. Connect to AGND through a ground plane.
G ate- D ver O utp ut B. C onnect N D RV B to the g ate of the exter nal N channel FE T.
Gate-Driver Output A. Connect NDRVA to the gate of the external N-channel FET.
