Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC4100BMTR is determined by strict equivalence across the following critical parameters:

• Driven configuration (half-bridge topology)
• Number of independent drivers (2 channels)
• Gate type (N-channel MOSFET)
• Supply voltage range (9V ~ 16V)
• Logic voltage thresholds (VIL = 3V, VIH = 8V)
• Peak output current capability (2A source, 2A sink)
• Input signal type (non-inverting)
• Maximum bootstrap voltage (118V)
• Switching characteristics (400ns rise/fall time)
• Package form factor (8-SOIC)
• Operating temperature range (-40°C ~ 125°C)

The MIC4100YM-TR meets all these criteria and is manufactured by the same supplier, ensuring functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MIC4100YM-TR is the direct functional equivalent of the MIC4100BMTR. Both devices share identical electrical specifications, switching characteristics, and package geometry. The primary distinction is product lifecycle status: the MIC4100BMTR is obsolete, while the MIC4100YM-TR is active and in production.

The MIC4100YM-TR additionally provides ROHS3 compliance, whereas the MIC4100BMTR is non-compliant. For applications requiring RoHS certification or long-term supply chain stability, the MIC4100YM-TR is the appropriate selection. Both devices are REACH unaffected and carry the same ECCN and HTSUS classifications.
