FAN3122CMPX

Gate Driver Overview

The FAN3122CMPX is a single low-side MOSFET gate driver from onsemi, designed for surface-mount applications in an 8-pin MLP package. It operates with a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 11.4 A. The device features non-inverting logic configuration with rise and fall times of 23 ns and 19 ns, respectively. It functions within an operating temperature range of -40°C to +125°C and consumes 650 µA of quiescent current.

Gate Driver Feature Summary

• Provides high peak output current capability for rapid MOSFET switching
• Features non-inverting input logic for direct control interface compatibility
• Operates reliably across extended industrial temperature ranges

Gate Driver Applications

• Power management systems requiring efficient low-side switching
• Industrial motor control circuits
• Automotive power distribution units

Gate Driver Procurement Notes

Verify the specific MLP-8 package variant against design requirements. Confirm supply voltage limits and thermal dissipation capabilities for the target application environment. Ensure input logic levels match the driving controller specifications. Check for RoHS compliance documentation if required by regulatory standards.

Gate Driver Selection Notes

Select this component when high peak drive current is necessary for low-side MOSFETs. Consider the 8-pin MLP footprint for space-constrained PCB layouts. Evaluate the 18 V maximum supply limit against system rail voltages. Assess thermal performance given the 396 mW power dissipation rating in the chosen enclosure.

Gate Driver Part Context

This part belongs to the FAN3122T series of gate drivers. It shares functional similarities with other low-side drivers like the FAN3100 but offers higher output current capacity. The MLP-8 package provides a compact solution compared to traditional SOIC or DIP formats while maintaining robust electrical performance for power switching applications.

Gate Driver Replacement Considerations

Direct substitutes include the FAN3122TMPX and FAN3122CMX variants, which share core electrical characteristics. Verify pinout compatibility and package dimensions before substitution. Ensure equivalent thermal and electrical ratings are maintained in alternative components.
