FAN3122TMX

Gate Driver Overview

The FAN3122TMX is a single low-side MOSFET gate driver from onsemi, housed in an MLP-8 surface-mount package. It delivers a peak output current of 9 A with a supply voltage range of 4.5 V to 18 V. The device features non-inverting logic and operates within a temperature range of -40°C to +125°C. Key timing parameters include a rise time of 23 ns and a fall time of 19 ns. Quiescent current is specified at 650 µA, with power dissipation rated at 396 mW.

Gate Driver Feature Summary

• High-speed switching capability with nanosecond-level rise and fall times for efficient power control.
• Robust 9 A output drive strength suitable for driving large power MOSFETs or IGBTs.
• Low quiescent current consumption to minimize standby power loss in battery-operated systems.

Gate Driver Applications

• Motor control systems requiring precise low-side switching.
• DC-DC converter topologies utilizing synchronous rectification.
• Inverter circuits for industrial automation and power supplies.

Gate Driver Procurement Notes

Verify the specific suffix 'TMX' against the manufacturer's official datasheet to confirm the MLP-8 package and tape-and-reel orientation. Ensure compatibility with your PCB footprint design for the MLP-8 form factor. Cross-reference RoHS compliance status directly with the component documentation prior to integration.

Gate Driver Selection Notes

Select this component when a single-channel, high-current low-side driver is required. The 9 A output current exceeds requirements for smaller loads, offering headroom for rugged operation. The wide supply voltage range supports various logic levels and bus voltages common in automotive and industrial environments.

Gate Driver Part Context

This part belongs to the FAN3122T series of high-speed gate drivers. It serves as a single-channel variant within onsemi's portfolio, distinct from dual-channel models like the FAN3224. The MLP-8 package provides a compact solution compared to traditional SOIC packages used in similar driver families.

Gate Driver Replacement Considerations

Direct substitutes may include other single low-side drivers from onsemi with comparable current ratings. Verify pinout compatibility and thermal performance before swapping. Consult the manufacturer's selection guide for alternative packages or updated revisions.
