FAN3225TMPX

Gate Driver Overview

The FAN3225TMPX is a dual high-speed low-side MOSFET gate driver manufactured by onsemi. It features two independent drivers with peak output currents of 4A source and sink capabilities. The device operates within a supply voltage range of 4.5V to 18V and supports both inverting and non-inverting input configurations. It utilizes an MLP-8 package for surface mount installation. Key timing parameters include a rise time of 12ns and a fall time of 9ns. The component functions reliably across an operating temperature range from -40°C to +125°C, incorporating internal undervoltage lockout protection.

Gate Driver Feature Summary

• Provides dual independent high-speed gate drive channels optimized for N-channel enhancement-mode MOSFETs.
• Features matched internal propagation delays between channels to ensure critical timing accuracy for synchronous rectification applications.
• Integrates internal undervoltage lockout circuitry that maintains outputs in a low state until the supply voltage reaches the specified operating threshold.

Gate Driver Applications

• Synchronous rectifier circuits requiring precise dual-channel timing alignment
• Low-side switching applications for power management systems
• Parallel driver configurations for increased current capability driving single MOSFETs

Gate Driver Procurement Notes

Verify the specific suffix 'TMPX' against the manufacturer's official datasheet to confirm the MLP-8 package type and tape-and-reel packaging configuration. Ensure compatibility with the required input logic thresholds (TTL or CMOS) as defined in the electrical characteristics table. Cross-reference the RoHS compliance status and lead times directly with authorized distributors prior to ordering.

Gate Driver Selection Notes

Select this component when dual low-side drive with matched propagation delay is required for synchronous applications. The 4A peak current rating suits moderate-power MOSFET switching. Consider the MLP-8 package constraints for PCB layout thermal dissipation. Verify that the 4.5V minimum supply voltage aligns with the system's available rail during startup conditions.

Gate Driver Part Context

This part belongs to the FAN322x series of dual high-speed low-side gate drivers designed by onsemi. The series includes variants with different output currents and input configurations, such as the FAN3227 and FAN3226. These drivers are engineered to provide high peak current pulses during short switching intervals for efficient N-channel MOSFET control.

Gate Driver Replacement Considerations

Publicly confirmed substitute part numbers for the FAN3225TMPX were not identified in the provided documentation. Evaluate alternative parts within the FAN322x family only if pinout and functional specifications match exactly.
