General Description

The uP1964 is designed to high-speed low-side driver for enhancement mode Gallium Nitride (GaN) transistors and MOSFETs application. With high source and sink output current capability, the uP1964 offers enhanced immunity against Miller turn-on effect.

The uP1964 has two separate gate outputs allowing independent adjustment of the turn-on and turn-off capability by adding impedance for gate loop. This part has fast switching speed and minimized propagation delays, facilitating high-frequency operation. The uP1964 can tailor different gate voltage requirements of GaN transistor or MOSFETs through VDRV. The gate driver output voltage level can be adjusted through external resistor voltage divider. The PWM input of this device is CMOS logic compatible and can withstand the input voltage up to 5.5V regardless of the VDRV voltage. This device also supports supply input under voltage lockout. The uP1964 is available in thermally enhanced WDFN3x3-10L.
