FAN7930CMX

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.

FAN7930CMX is a three-phase brushless DC motor gate driver. Key features include:
- Six outputs: HO1/LO1, HO2/LO2, HO3/LO3 for three half-bridges
- Bootstrap high-side drive with internal charge pump
- Undervoltage lockout on logic and gate-drive supplies
- Overcurrent/short-circuit protection with current limit
- Thermal shutdown with automatic retry
- Cross-conduction protection and built-in dead-time
- Fault diagnostics/flag outputs for status monitoring
- Logic-compatible inputs (0–5 V style) with fast response
- Quiet standby with low quiescent current
- CMX package, suitable for wide operating temperature (typically -40°C to 125°C)
Applications: BLDC motor drive in consumer and industrial equipment. Note: specifics (voltage/current ratings, exact pinout) vary by revision; consult the datasheet for exact electrical specs.

Pin count: 8 pins (CMX package).
Function: Dual high/low-side MOSFET gate driver for switch-mode power supplies (SMPS). It provides two gate drive outputs (for high-side and low-side MOSFETs) controlled by input logic, with built-in protection features (e.g., undervoltage lockout).

- Manufacturer: Fairchild Semiconductor (now part of ON Semiconductor).
- What kind of company: A multinational semiconductor company that designs and manufactures integrated circuits and power-management devices.
