MIC4469ZWM

Overview

The MIC4469ZWM is a quad low-side MOSFET gate driver from Microchip Technology, housed in a 16-pin SOIC package. It delivers a peak output current of 1.2 A with rise and fall times of 25 ns. The device operates on a supply voltage range of 4.5 V to 18 V and draws a working supply current of 4 mA. It supports an operating temperature range from 0°C to +70°C and features CMOS logic input compatibility.

Feature Summary

• Integrates four independent low-side drivers with dual input logic gates for added flexibility
• Built using BCD process technology ensuring latch-up protection and noise immunity
• Capable of driving highly capacitive loads such as power MOSFETs with high efficiency
• Accepts inductive kickback current without damage or logic upset

Applications

• Driving power MOSFETs and similar highly capacitive loads
• Driving heavily loaded clock lines
• Driving coaxial cables
• Driving piezoelectric transducers

Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's official documentation to confirm lead-free status and RoHS compliance details. Confirm that the SOIC-16 package matches your PCB footprint requirements. Check for moisture sensitivity level (MSL) handling instructions if the component has been exposed to ambient conditions prior to assembly.

Selection Notes

Select this component when a system requires four independent low-side drivers in a single package to reduce board space and cost. It is suitable for applications needing fast switching speeds and high peak currents. Ensure the load capacitance and total power dissipation remain within the specified limits for the SOIC-16 package.

Part Context

The MIC4469ZWM belongs to the MIC446x family of quad output CMOS buffer/drivers. This series expands upon earlier single and dual-output designs by utilizing higher pin count packages to include dual input logic gates. The family aims to improve system reliability and reduce total system cost by replacing multiple packages and associated logic components.
