FUNCTION
Gate-Drive Output. Nominal GATE load is a 0.01μF capacitor to ground. Gate is discharged to GND in
shutdown.
Ground
Low-Voltage Optional Input Power. Leave disconnected when V DD = 8V to 13.25V, or connect V DD to VL
when V DD = 3V to 5.5V. Bypass VL to GND with a 0.01μF capacitor.
Power-Supply Input. Connect to an 8V to 13.25V supply or connect to VL when using a 3V to 5.5V supply.
Bypass V DD with a 0.01μF capacitor to ground.
Undervoltage-Protection Input. Connect UVP to the center of a resistor-divider from CS+ to GND. Connect
UVP to VL to disable the undervoltage protection.
Timer Input. Connect a resistor from TIMER to GND to select the charge-pump operating frequency. Drive
TIMER low (< 0.5V) to disable the gate drive. Drive TIMER high (above 1.5V) for charge-pump operation
at 550kHz.
Open-Drain Fault Output. FAULT is high impedance during normal operation and is pulled to GND when a
fault condition occurs. Connect a pullup resistor of 10k ? or higher value (50k ? typ) to a voltage rail of 5.5V
or lower.
Overvoltage-Protection Input. Connect OVP to the center of a resistor-divider from the output bus to GND.
Connect OVP to GND to disable the overvoltage protection.
Current-Sensing Input. Connect CS- to the positive side of the system bus. Bypass with a 1000pF capacitor
to GND.
Current-Sensing Input. Connect CS+ to the positive side of the input power. Bypass with a 1000pF capacitor
to GND.
