MIC4469CWM TR

Overview

The MIC4469CWM TR is a quad low-side MOSFET gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 1.2 A. The device features independent drivers with rise and fall times of 25 ns each. It is housed in a 16-SOIC package and supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Quad low-side configuration for driving power MOSFETs
• High peak output current capability of 1.2 A
• Fast switching performance with 25 ns rise and fall times
• Latch-up protection exceeding 500 mA reverse current

Applications

• Driving power MOSFETs and similar highly capacitive loads
• Heavily loaded clock line buffering
• Coaxial cable driving applications

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging, as standard datasheets may reference tube packaging for the base part number. Confirm RoHS compliance status, as some variants are marked non-compliant. Check current lifecycle status, as this component family includes discontinued parts. Ensure the supplier provides valid traceability documentation for the reel quantity.

Selection Notes

Select this component when four independent low-side drivers are required in a single package. It is suitable for applications needing high efficiency and rail-to-rail voltage swings. Consider the 16-SOIC package constraints and thermal dissipation limits. Verify that the input logic levels match the system CMOS requirements.

Part Context

This part belongs to the MIC446x family of quad buffer/drivers. It expands on earlier single and dual-output designs by utilizing available pin count for dual input logic gates. This integration improves system reliability and reduces total system cost by replacing multiple packages and associated logic components.

Replacement Considerations

MIC4469YWM is listed as a direct replacement for the MIC4469BWM variant. TC4469CPD and TC4469EPD are noted as similar alternatives. Verify pinout compatibility and electrical specifications before substitution.
