MIC4426YMM

Overview

The MIC4426YMM is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features two independent inverting channels with peak output currents of 1.5A source and sink. The device operates within a supply voltage range of 4.5V to 18V and supports CMOS and TTL logic inputs with thresholds at 0.8V and 2.4V. Typical rise and fall times are 20ns and 29ns respectively. It is housed in an 8-MSOP package and functions across a junction temperature range of -40°C to 150°C.

Feature Summary

• Dual-channel low-side configuration for independent MOSFET control

Procurement Notes

Verify the specific suffix 'YM' indicates the MSOP package variant distinct from other package options like SOIC or DFN. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the supplier provides valid traceability documentation matching the Microchip manufacturing standards.

Selection Notes

Select this component when dual low-side driving is required with high current capability. Consider the MSOP package constraints for PCB space. Evaluate the 1.5A peak current against load requirements. Verify logic voltage compatibility with the controlling microcontroller or FPGA before integration into the circuit design.
