Use a resistor network to set the output voltage from +2.0V to +5.5V.
If FB=V
Low-Battery Comparator Input. Internally set to trip at +1.30V.
Open-Drain Low-Battery Comparator Output. Connect LBO to OUT through a 100kΩ resistor.
Output is low when V
1.2V Reference Voltage. Bypass with a 0.1μF capacitor.
Power Output. OUT provides bootstrap power to the IC.
N-Channel and P-Channel Power MOSFET Drain
Ground
Shutdown Input. Drive high (>80% of V
shutdown mode. Connect to OUT for normal operation.
Current-Limit Select Input. CLSEL = OUT sets the current limit to 0.8A. CLSEL = GND sets the
current limit to 0.4A.
Battery Input and Damping Switch Connection. If damping switch is unused, leave BATT
unconnected.
