Drives the gate of a power MOSFET or IGBT from a logic signal, sourcing 4 A and sinking 8 A to switch it quickly and cut switching loss. Separate OUTH and OUTL pins let a resistor set the turn-on and turn-off speeds independently, and the inputs are TTL/CMOS compatible with hysteresis and an inverting option (IN-, IN+). Propagation delay is about 13 ns. A small, fast low-side driver for switch-mode supplies and motor stages.

Pinout

Pin	Name	Type	Function
1	VDD	power_in	Bias supply input. Operating range 4.5 V to 18 V. Internal UVLO holds outputs low outside operating range.
2	OUTH	output	Sourcing current output of driver (4-A peak source). Connect a resistor between OUTH and the gate of the power-switching device to adjust turn-on speed.
3	OUTL	output	Sinking current output of driver (8-A peak sink). Connect a resistor between OUTL and the gate of the power-switching device to adjust turn-off speed. Low pulldown impedance ~0.375 Ω.
4	GND	power_in	Ground reference. All signals referenced to this pin.
5	IN-	input	Inverting input. When the driver is used in noninverting configuration, connect IN- to GND to enable the output. Output is held LOW if IN- is unbiased or floating (internal pullup/pulldown).
6	IN+	input	Noninverting input. When the driver is used in inverting configuration, connect IN+ to VDD to enable the output. Output is held LOW if IN+ is unbiased or floating (internal pullup/pulldown).
