MIC4425YWM

Overview

The MIC4425YWM is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features two independent drivers with peak output currents of 3 A each, housed in a 16-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 18 V and supports CMOS and TTL logic inputs. It exhibits rise and fall times of approximately 28 ns to 35 ns, depending on load conditions. The component is rated for an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides high-speed switching capability with low propagation delay for efficient power management
• Delivers robust 3 A peak source/sink current to rapidly charge and discharge MOSFET gates
• Incorporates enhanced noise immunity to withstand ground pin spiking without latch-up or logic upset

Applications

• High-frequency DC-DC converter topologies requiring fast switching speeds
• Motor control systems utilizing low-side N-channel MOSFETs
• Industrial power supplies and inverters demanding reliable gate drive performance

Procurement Notes

Verify the specific suffix 'YWM' corresponds to the SOIC-16 package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status as historical data indicates variations across the MIC4425 family. Ensure the supplier provides valid traceability documentation, particularly if sourcing from third-party distributors or surplus channels, as availability may vary.

Selection Notes

Select this component when a dual low-side driver with 3 A output current is required. It is suitable for applications needing compatibility with standard CMOS and TTL logic levels. Consider the SOIC-16 package constraints for PCB layout. Compare against the MIC4425ZWM if a commercial temperature range (0°C minimum) is sufficient, or the MIC4425CWM for leaded options, ensuring thermal and electrical specifications match the design requirements.

Part Context

The MIC4425YWM belongs to the MIC4423/4424/4425 family of BiCMOS/DMOS MOSFET drivers. These devices are pin-compatible with the earlier MIC426/427/428 series but offer improved reliability and higher output current capabilities. The family is designed to operate reliably in demanding electrical environments, featuring protection against latch-up and significant noise spikes on the ground pin.

Replacement Considerations

MIC4425ZWM: Commercial temperature grade (0°C min). MIC4425CWM: Lead-based packaging variant. MIC4425YWM-TR: Tape and reel version of the same device.
