FAN3182BMX

Gate Driver Overview

The FAN3182BMX is a high-speed, single-channel half-bridge gate driver manufactured by onsemi. It is designed to drive power MOSFETs and IGBTs in hard-switching applications such as motor control, DC-DC converters, and lighting ballasts. The device features a robust output stage capable of delivering peak currents of 2A source and 4A sink. It operates with a supply voltage range from 4.5V to 18V and includes built-in protections against under-voltage lockout (UVLO) and shoot-through conditions via programmable dead-time control.

Gate Driver Feature Summary

• Integrated programmable dead-time control to prevent shoot-through in half-bridge configurations
• High peak output current capability for efficient switching of power devices
• Built-in under-voltage lockout protection ensures safe operation during power-up and power-down sequences

Gate Driver Applications

• Motor control systems
• DC-DC converter circuits
• Lighting ballast drivers

Gate Driver Procurement Notes

Verify the specific suffix 'BMX' corresponds to the required tape-and-reel packaging configuration. Confirm that the operating temperature range and pinout compatibility match the target PCB layout. Ensure that the input logic voltage levels are compatible with the controlling microcontroller or PWM signal source before finalizing the procurement order.

Gate Driver Selection Notes

Select this component when a single-channel half-bridge driver with integrated dead-time management is required. It is suitable for applications needing moderate switching speeds and reliable protection against cross-conduction. Consider alternative models if higher peak currents or dual-channel integration are necessary for the specific power stage design.
