FAN73912MX

Gate Driver Overview

The FAN73912MX is a high-voltage half-bridge gate driver IC manufactured by onsemi, designed for driving N-channel MOSFETs and IGBTs. It features a dual non-inverting input configuration with synchronous channel operation in a 16-SOIC package. The device supports a maximum bootstrap voltage of 1200 V and operates within a supply voltage range of 12V to 20V. Peak output currents are specified at 2A sink and 3A source. Typical rise and fall times are 25ns and 15ns respectively. Logic thresholds are defined at 6V (VIL) and 9.5V (VIH). The component functions across a junction temperature range of -40°C to 125°C.

Gate Driver Feature Summary

• High-voltage capability supporting up to 1200 V bootstrap operation for industrial power applications
• Synchronous half-bridge architecture with dedicated high-side and low-side drivers
• Robust switching performance with fast typical rise and fall times for efficient power control

Gate Driver Applications

• Industrial motor drives
• Inverter circuits
• Switched-mode power supplies

Gate Driver Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type, as variations such as tape-and-reel or cut-tape exist under the same base part number. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into surface-mount assembly processes to ensure manufacturing compatibility.

Gate Driver Selection Notes

Select this component when designing systems requiring high-voltage isolation and robust gate drive capabilities for N-channel devices. Ensure the application logic levels align with the specified 6V and 9.5V thresholds. Verify that the thermal management strategy accommodates the 125°C maximum junction temperature rating during continuous operation.

Gate Driver Part Context

This device belongs to the FAN73912 series of high-voltage gate drivers from onsemi. It is distinct from lower-voltage variants like the FAN7380 or FAN7390, which offer different pin counts and voltage ratings. The 16-SOIC package provides a compact solution for integrating half-bridge topologies in space-constrained power electronics designs.
