ZXGD3003E6
5A(peak) gate driver in SOT23-6
General description
The ZXGD3003E6 is a high-speed non-inverting single MOSFET gate driver capable of driving up to 5A
into a MOSFET or IGBT gate capacitive load from supply voltages up to 40V. With typical propagation
delay times down to 2ns and rise/fall times down to 9ns this device ensures rapid switching of the power
MOSFET or IGBT to minimize power losses and distortion in high current fast switching applications.
The ZXGD3003E6 is inherently rugged to latch-up and shoot-through, and its wide supply voltage range
allows full enhancement to minimize on-losses of the power MOSFET or IGBT.
Its low input voltage requirement and high current gain allows high current driving from low voltage
controller ICs, and the optimized pin-out SOT23-6 package with separate source and sink pins eases
board layout, enabling reduced parasitic inductance and independent control of rise and fall slew rates.
