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