Function
Ground
Input. Defines whether the high-side (HS) or low-side (LS) switch is activated.
Inhibit. When set to LOW, the device enters Sleep Mode and resets Over-
Temperature Protection (OTP) and the HS and LS short latch.
Power output of the bridge
Slew rate. The slew rate of the power switches can be adjusted by connecting a
resistor between the SR and GND pins.
