MIC4468BWM Equivalent & Substitute Parts Reference

Part Overview

The MIC4468BWM, manufactured by Microchip Technology, is a Power Management Integrated Circuit (PMIC) specifically designed as a low-side gate driver IC for N-Channel and P-Channel MOSFETs. It features four independent drivers, with non-inverting input logic, operating over a supply voltage range of 4.5V to 18V, a peak output current of 1.2A (source and sink), and logic threshold of 0.8V (VIL) and 2.4V (VIH). Key attributes include fast switching (14ns rise, 13ns fall times), a surface mount 16-SOIC package, and an operating temperature of -40°C to 85°C. The device is classified as obsolete, prompting the need for alternative or replacement model selection to maintain supply continuity or fulfill new design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MIC4468BWM is determined strictly by matching the following key parameters: manufacturer, category, gate driver configuration (low-side), number of drivers (4), channel type (independent), gate type (N-Channel, P-Channel MOSFET), supply voltage range (4.5V ~ 18V), logic threshold levels (VIL and VIH), peak output current (source and sink), rise and fall times, input type, operating temperature range, mounting type, package/case dimensions, and compliance status. No substitution is considered unless all these parameters are equivalent.
