MIC4427CM-TR

Overview

The MIC4427CM-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features two independent non-inverting channels housed in an 8-SOIC package. The device supports supply voltages from 4.5V to 18V and delivers peak output currents of 1.5A for both sourcing and sinking. Typical rise and fall times are 20ns and 29ns, respectively. It operates within a junction temperature range of 0°C to 150°C and accepts CMOS or TTL logic inputs with thresholds at 0.8V and 2.4V.

Feature Summary

• Dual independent low-side drive configuration
• High peak current capability for fast switching
• Non-inverting input logic compatibility

Applications

• Low-side MOSFET switching control
• Power management circuits
• Motor drive interfaces

Procurement Notes

Verify the suffix 'CM' indicates commercial temperature grade (0°C to 150°C TJ) versus industrial variants like 'YM'. Confirm RoHS3 compliance status. Check moisture sensitivity level handling requirements during assembly. Ensure the TR suffix matches reel specifications for automated placement equipment.

Selection Notes

Select this component when dual low-side driving is required with high peak current needs. Compare against MIC4426 for inverted logic options. Consider MIC4428 if high-side or half-bridge capabilities are needed instead. Verify voltage ratings align with the target MOSFET gate requirements.

Part Context
