概要
Description
FAN7930CMX is a dual-channel high- and low-side MOSFET gate driver. It’s designed to drive a high-voltage half-bridge (two N‑channel MOSFETs) in applications like motor drives and switch-mode power supplies.
Key features (typical):
- Bootstrap high-side drive with dedicated HO and LO outputs
- UVLO and overcurrent/shoot-through protection
- Dead-time control to prevent cross-conduction
- TTL/CMOS-compatible input logic
- Compact CMX package variant
How it works:
- The low-side channel drives the lower MOSFET; the bootstrap capacitor provides the gate voltage for the high-side channel, enabling switching a high-side MOSFET.
Typical applications:
- BLDC/stepper motor drives, motor control Inverters, DC-DC converters, and other power-switching circuits requiring a high-voltage half-bridge driver.
Note:
- For exact electrical specs, pinout, and package details (voltages, timing, currents), consult the FAN7930CMX datasheet from the manufacturer.
