MIC4468BN Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The MIC4468BN is a low-side gate driver IC manufactured by Microchip Technology, designed for driving N-Channel and P-Channel MOSFETs in power management applications. This 14-DIP through-hole component operates across a 4.5V to 18V supply voltage range with independent channel configuration supporting up to 4 drivers per package.

The MIC4468BN is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. The MIC4468YN serves as the direct active substitute, maintaining identical electrical and mechanical specifications while offering improved compliance status and current availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC4468BN with the MIC4468YN is based on strict equivalence across all critical electrical and mechanical parameters. Both parts share identical specifications in the following key areas:

• Driven configuration (Low-Side)
• Channel type and quantity (4 independent drivers)
• Gate type compatibility (N-Channel, P-Channel MOSFET)
• Supply voltage range (4.5V ~ 18V)
• Logic voltage thresholds (VIL 0.8V, VIH 2.4V)
• Peak output current (1.2A source, 1.2A sink)
• Input signal type (Non-Inverting)
• Switching performance (14ns rise, 13ns fall time)
• Operating temperature range (-40°C ~ 85°C)
• Physical package (14-DIP, 0.300" pitch, 7.62mm)
• Moisture sensitivity classification (MSL 1)

The MIC4468YN differs only in product status (Active vs. Obsolete) and compliance certifications, making it a direct functional and pin-compatible replacement.

Parameter Comparison

Engineering Selection Recommendations

The MIC4468YN is the appropriate selection for applications currently using or specifying the MIC4468BN. The substitution is valid based on complete electrical and mechanical equivalence across all provided parameters.

The MIC4468YN offers the additional advantage of ROHS3 compliance, whereas the MIC4468BN is RoHS non-compliant. For applications subject to RoHS regulatory requirements or customer specifications mandating RoHS compliance, the MIC4468YN is the required choice.

Both parts maintain identical REACH and ECCN classifications, ensuring equivalent regulatory treatment in export and supply chain contexts.
