FAN3278TMX

Gate Driver Overview

The FAN3278TMX is a low-voltage PMOS-NMOS bridge driver manufactured by onsemi, designed for high-side and low-side MOSFET control. It operates within an 8V to 27V supply range, with a maximum output voltage of 30V. The device features two drivers with inverting and non-inverting configurations, delivering peak output currents of 1.5A sink and 1.0A source. Key timing parameters include rise and fall times of 17ns and 8ns respectively. It functions reliably across a temperature range of -40°C to +125°C and is housed in an SOIC-8 package.

Gate Driver Feature Summary

• Integrated internal regulator optimizes gate drive voltage for efficient switching within the specified operating range.
• Built-in logic level shifting and buffering accommodate various TTL input signals with defined hysteresis.
• Automatic shutdown mechanism prevents unintended MOSFET conduction during power-up or undervoltage conditions.

Gate Driver Applications

• Motor control systems requiring high-side P-channel and low-side N-channel MOSFET driving
• DC-DC buck converter topologies utilizing external MOSFETs
• Industrial power management circuits

Gate Driver Procurement Notes

Verify the specific suffix TMX corresponds to the required tape and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOIC-8 footprint matches the target PCB layout specifications exactly.

Gate Driver Selection Notes

Select this component when designing circuits that require simultaneous control of both high-side PMOS and low-side NMOS devices. The dual-channel architecture supports bridge configurations efficiently. Consider the 8V minimum operating voltage constraint when choosing the power supply rail for the driver IC itself.
