Overview
The MIC4425YM-TR is a dual low-side MOSFET gate driver from the MIC4425 family, manufactured by Microchip Technology. It features two independent drivers with inverting and non-inverting outputs, housed in an SOIC-8 package. The device delivers a peak output current of 3 A and operates within a supply voltage range of 4.5 V to 18 V. It exhibits fast switching characteristics with rise and fall times of 15 ns. The component supports CMOS and TTL logic inputs and functions reliably at temperatures between -40°C and +85°C.
Feature Summary
- Dual-channel architecture providing both inverting and non-inverting output configurations for flexible circuit design.
- High-speed switching performance with 15 ns rise and fall times to minimize switching losses.
- Robust noise immunity capable of surviving up to 5V of ground pin noise spiking without latch-up or logic upset.
Applications
- Low-side MOSFET driving in DC-DC converters
- Motor control applications requiring high peak current
- General-purpose buffer and inverter circuits
Procurement Notes
Verify the specific suffix 'YM-TR' to confirm the SOIC-8 package and tape-and-reel packaging format. Ensure compatibility with existing PCB footprints designed for 8-pin surface-mount devices. Confirm that the operating temperature range meets the environmental requirements of the target application.
Selection Notes
Select this component when a dual low-side driver with distinct inverting and non-inverting outputs is required. The 3 A peak current capability suits moderate-power MOSFETs. Consider the SOIC-8 package size constraints and the need for fast switching speeds in power conversion topologies.
Part Context
The MIC4425YM-TR belongs to the MIC4425 family of BiCMOS/DMOS drivers, which are higher output current versions of the MIC4426/4427/4428 series. These drivers are pin-compatible with predecessor families and offer improved reliability in demanding electrical environments compared to earlier generations.
Replacement Considerations
The MIC4425ZWM-TR serves as a pin-compatible alternative within the same family, offering identical functionality but packaged in a 16-pin SOIC format rather than the 8-pin SOIC used by the MIC4425YM-TR.
