Typical Operating Characteristics (continued)
Input. Bypass with a 0.1µF ceramic capacitor to ground as close to the device
as possible.
Ground
Active-High, Switch-On Input. A logic-high turns the switch on.
Fault Output. This open-drain output goes low when the device stays in
forward or reverse current limit for more than the blanking time period. FLAG is
high impedance when a fault is not present or when ON is low.
Switch Output. Bypass with a 0.1µF ceramic capacitor to ground as close to
the device as possible.
No Connection. Not internally connected.
