Single-Channel GaN Driver

The INS1001 is designed to drive single-channel GaN FET(s) in either low-side, high-side, or secondary-side SR applications. It has both non-inverting and inverting PWM inputs, working with controller, opto-coupler, and digital isolator flexibly. The gate driver has two separate outputs, allowing independent adjustment of turn-on and turn-off speeds. The driver voltage can be adjusted through an external resistor divider, tailoring for different gate voltage requirements of GaN FETs. Integrated 5V LDO can supply digital isolator or other circuitry in high-side applications. The strong driving capability and fast propagation delay, along with input noise deglitching and built-in UVLO, OVP, OTP protection features, make the INS1001 extremely suitable for high power, high frequency, and robust power GaN applications. The INS1001 is available in thermally enhanced DFN3x3-10L package.
