FAN3121TMPX

Gate Driver Overview

The FAN3121TMPX is a single high-speed low-side gate driver manufactured by onsemi. It provides a peak output current of 9A and operates within an input voltage range of 4.5V to 20V. The device supports supply voltages from 10V to 20V and features a fixed delay time of 60ns with a matching rise and fall time of 25ns. It includes built-in under-voltage lockout protection and functions as a non-inverting buffer or inverter based MOSFET driver. The component is housed in an MLP-8 package, rated for operation between -40°C and +125°C, and complies with RoHS standards.

Gate Driver Procurement Notes

Verify the specific ordering suffix against the official onsemi database to ensure correct packaging and tape-and-reel specifications. Confirm that the MLP-8 package variant matches your PCB footprint requirements. Check for any recent Fairchild integration updates regarding part number nomenclature changes. Ensure the component meets the required environmental compliance standards for your target market.

Gate Driver Selection Notes

Select this component when a single-channel low-side driver with high peak current capability is required. It is suitable for applications demanding fast switching speeds with minimal skew. Consider the MLP-8 package size for space-constrained designs. Verify that the input logic levels are compatible with the control circuitry driving the gate.

Gate Driver Part Context
