PIN I/O DESCRIPTION
NO. NAME
1 ENBA I Enable input for the driver A with logic-compatible threshold and hysteresis. The driver output can be enabled and disabled with this pin. It is internally pulled up to VDD with 100-kΩ resistor for active high operation. The output state when the device is disabled is low, regardless of the input state.
2 INA I Input A. Input signal of the A driver which has logic-compatible threshold and hysteresis. If not used, this input must be tied to either VDD or GND. It must not be left floating.
3 GND — Common ground. This ground must be connected very closely to the source of the power MOSFET which the driver is driving.
4 INB I Input B. Input signal of the B driver which has logic-compatible threshold and hysteresis. If not used, this input must be tied to either VDD or GND. It must not be left floating.
5 OUTB O Driver output B. The output stage is capable of providing 4-A drive current to the gate of a power MOSFET.
6 VDD — Supply voltage and the power input connection for this device.
7 OUTA O Driver output A. The output stage is capable of providing 4-A drive current to the gate of a power MOSFET.
8 ENBB I Enable input for the driver B with logic-compatible threshold and hysteresis. The driver output can be enabled and disabled with this pin. It is internally pulled up to VDD with 100-kΩ resistor for active-high operation. The output state when the device is disabled is low, regardless of the input state.
