概述
Description
FAN7389MX1 is a dual-channel gate-driver IC from the FAN7389 family designed to drive N-channel MOSFETs in a half-bridge. It provides bootstrap-powered high-side (HO) and low-side (LO) gate outputs, driven from logic inputs, to enable fast, synchronized switching in motor drives, inverters, and switching power supplies. A bootstrap circuit lets the high-side gate be driven above the supply voltage, allowing operation from higher bus voltages. The device includes essential protections and controls such as undervoltage lockout, dead-time control to prevent shoot-through, and a shutdown input for safe disablement. The MX1 suffix denotes a specific package/revision variant. For exact electrical specs (VCC range, UVLO thresholds, timing, bootstrap capacitor requirements, and MOSFET recommendations), refer to the FAN7389MX1 datasheet.
Features
Here are the main features of FAN7389MX1 (gate-driver for half-bridge):
- Dual channel high-side/low-side gate driver for bootstrap topology (drives HO and LO).
- Independent inputs IN1 and IN2 with corresponding outputs HO and LO.
- Bootstrap high-side drive using VB and VS; logic supplied from VCC/COM.
- Wide voltage range with 600V capability for VS and VB-VS operation.
- UVLO (undervoltage lockout) on VCC and VB to prevent misdrive, with hysteresis.
- Shoot-through protection and dead-time control to prevent cross-conduction.
- Fast gate-drive capability with high peak current for quick switching of MOSFETs/IGBTs.
- Fault protection features (including undervoltage protection) and robust protection for safe operation.
- 16-pin package (MX1 variant) suitable for compact motor/inverter designs.
Note: Always refer to the datasheet for exact electrical specs (thresholds, timing, and package options) for your specific application.
