MIC4469BWM TR

Overview

The MIC4469BWM-TR is a quad low-side MOSFET gate driver manufactured by Microchip Technology. It features four independent drivers in a 16-SOIC package, delivering a peak output current of 1.2 A. The device operates on a supply voltage range of 4.5 V to 18 V with non-inverting logic inputs. Typical rise and fall times are 13 ns and 14 ns respectively. It supports both N-channel and P-channel MOSFETs and includes dual input logic gates for flexibility.

Feature Summary

• Provides four independent low-side driver channels within a single integrated circuit.
• Features dual input logic gates per channel to enhance design flexibility.
• Built using BCD process technology ensuring latch-up protection under rated conditions.

Applications

• Driving power MOSFETs in high-efficiency switching applications
• Driving highly capacitive loads requiring fast switching times
• Replacing multiple single-input driver packages to reduce system cost

Procurement Notes

Verify the specific suffix and manufacturer documentation carefully as this component may be discontinued or obsolete. Confirm RoHS compliance status and availability through authorized distributors. Ensure the ordering information matches the exact package type and temperature rating required for your application before purchase.

Selection Notes

Select this component when a compact solution for driving multiple low-side MOSFETs is required. It is suitable for applications needing high peak current capability and fast switching speeds. Consider the thermal dissipation limits of the SOIC-16 package relative to the total power requirements of the driven loads.

Part Context

This part belongs to the MIC4467/8/9 family of quad output CMOS buffer/drivers. It expands upon earlier single and dual-output driver designs by utilizing the available pin count to provide four high-power drivers. This integration improves system reliability and reduces the overall bill of materials compared to using discrete driver solutions.
