MIC4469ZWMTR

Overview

The MIC4469ZWMTR 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 for both sourcing and sinking. The device features independent complementary outputs with rise and fall times of approximately 25 ns. It is housed in a 16-lead SOIC package and is designed for surface-mount installation. The component supports CMOS logic inputs and functions as an inverting and non-inverting driver configuration.

Feature Summary

• Provides four independent low-side drive channels for N-channel and P-channel MOSFETs
• Features complementary inverting and non-inverting input configurations
• Delivers high peak output current capability for rapid switching
• Operates with standard CMOS logic voltage levels

Applications

• Low-side MOSFET switching in power conversion circuits
• Motor control systems requiring independent channel drive
• Industrial power management applications
• Automotive electronics utilizing low-side driving topologies

Procurement Notes

Verify the specific suffix ZWMTR against official Microchip documentation to confirm tape-and-reel packaging and temperature grade. Confirm RoHS compliance status as historical data indicates potential non-compliance for certain variants. Validate that the intended application environment falls within the specified operating temperature range. Ensure ESD handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select this component when four independent low-side drivers are required in a compact SOIC package. Consider the 1.2 A peak current rating for driving moderate capacitive loads. Verify that the input logic levels match the system's CMOS interface requirements. Evaluate the trade-off between the 25 ns switching speed and electromagnetic interference needs compared to faster alternatives.

Part Context

The MIC4469 series belongs to Microchip's family of quad low-side MOSFET drivers. This specific part number denotes the tape-and-reel variant of the MIC4469ZWM. It shares functional similarities with other members like the MIC4469BWM but differs in packaging and potentially temperature specifications. The series is designed for efficient power switching applications requiring multiple independent channels.

Replacement Considerations

The MIC4469YWM is identified as a direct replacement option. Verify pinout compatibility and electrical parameter alignment before substitution. Check if the replacement part meets the same packaging and reel requirements for existing assembly lines.
