MIC4422ABM-TR Equivalent & Substitute Parts

Part Overview

The MIC4422ABM-TR is a low-side gate driver IC manufactured by Microchip Technology, designed for driving N-channel MOSFETs in power management applications. This non-inverting single-channel driver operates across a 4.5V to 18V supply range with peak output currents of 9A (source and sink). The device is packaged in an 8-SOIC surface mount package.

The MIC4422ABM-TR is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC4422ABM-TR is determined by strict equivalence across the following critical parameters:

• Driven configuration (low-side operation)
• Single-channel architecture
• N-channel MOSFET gate drive capability
• Supply voltage range (4.5V ~ 18V)
• Logic input thresholds (VIL = 0.8V, VIH = 3V)
• Peak output current specifications (9A source and sink)
• Non-inverting input logic
• Rise and fall time characteristics (20ns, 24ns typical)
• Operating temperature range (-40°C ~ 150°C)
• 8-SOIC package footprint and pinout compatibility

The MIC4422AYM-TR meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MIC4422AYM-TR is the direct substitute for the MIC4422ABM-TR. Both parts share identical electrical specifications and package configurations, ensuring pin-for-pin and functional compatibility.

The primary distinction between these parts is product status and regulatory compliance. The MIC4422ABM-TR is discontinued, while the MIC4422AYM-TR maintains active production status. Additionally, the MIC4422AYM-TR is ROHS3 compliant, whereas the MIC4422ABM-TR is RoHS non-compliant. For new designs and production applications requiring RoHS compliance, the MIC4422AYM-TR is the appropriate selection.

Both parts carry identical REACH and ECCN classifications (REACH Unaffected, EAR99), and both have MSL rating of 1 (Unlimited moisture sensitivity level).
