MIC4468CWM TR

Overview

The MIC4468CWM-TR is a quad low-side MOSFET gate driver manufactured by Microchip Technology. It features four independent non-inverting outputs capable of delivering a peak output current of 1.2 A for both sourcing and sinking. The device operates within a supply voltage range of 4.5 V to 18 V and utilizes a 16-SOIC surface-mount package. Typical rise and fall times are specified at 14 ns and 13 ns, respectively. It is designed for driving power MOSFETs and other highly capacitive loads with high efficiency.

Feature Summary

• Integrates four independent low-side drivers in a single package to reduce system component count
• Provides high peak output current capability for efficient switching of power MOSFETs
• Includes built-in 2-input logic gates for added flexibility in control applications

Applications

• Driving power MOSFETs in industrial motor control systems
• Switching heavily loaded clock lines and coaxial cables
• Driving piezoelectric transducers requiring fast switching times

Procurement Notes

Verify the specific suffix 'TR' against official documentation, as standard listings often indicate tube packaging for this part number. Confirm RoHS compliance status, as some variants may not meet current environmental standards. Check lead time requirements carefully due to potential manufacturing delays. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Selection Notes

Select this component when multiple low-side drivers are required in a compact form factor. It serves as a direct replacement for older single or dual-output driver packages, reducing total system cost. Consider the 1.2 A peak current rating for load requirements. Verify that the 16-SOIC footprint fits the PCB layout constraints effectively.

Part Context

This device belongs to the MIC4467/4468/4469 family of quad CMOS buffer/drivers. These drivers expand upon earlier single and dual-output designs by utilizing available pin count to add logic gates. The family is optimized for high-efficiency, low-impedance driving of capacitive, resistive, or inductive loads with rail-to-rail voltage swings.
