Overview
The MIC4425CN is a dual low-side MOSFET gate driver manufactured by Microchip Technology, housed in an 8-pin PDIP package. It delivers a peak output current of 3A with rise and fall times of 25ns. The device operates within a supply voltage range of 4.5V to 18V and supports TTL logic inputs. It features latch-up protection exceeding 500mA reverse current and withstands input swings down to -5V.
Feature Summary
- Dual-channel architecture providing independent control for two low-side MOSFETs
- High peak output current capability of 3A for rapid switching
- Robust latch-up protection against reverse current conditions
- TTL-compatible logic inputs that function independently of the supply voltage
Applications
- Driving low-side power MOSFETs in motor control circuits
- Gate driving applications in DC-DC converters
- Power management systems requiring fast switching speeds
- Industrial automation equipment utilizing high-current loads
Procurement Notes
Verify the specific suffix 'CN' against official Microchip documentation to confirm the exact temperature grade and packaging configuration. Ensure compatibility with existing PCB footprints for the 8-pin PDIP format. Cross-reference datasheet revisions to confirm pinout consistency with previous generations of the MIC442x family.
Selection Notes
Select this component when a dual low-side driver with 3A peak current is required. It is suitable for designs needing TTL logic compatibility and wide operating voltage ranges. Consider the PDIP package for through-hole assembly requirements. Evaluate thermal performance based on the expected load capacitance and switching frequency.
Part Context
The MIC4425CN belongs to the MIC4423/4424/4425 family of highly reliable BiCMOS/DMOS buffer/driver/MOSFET drivers. This family represents higher output current versions of the MIC4426/4427/4428 series. All members of this family are pin-compatible, facilitating design upgrades or replacements within the same ecosystem.
Replacement Considerations
Compatible substitutes include MIC4423CN, MIC4424CN, and MIC4425CN variants due to shared pinouts. The MIC4426CN, MIC4427CN, and MIC4428CN are also pin-compatible but offer lower output currents. Verify functional differences such as inversion configurations before substitution.
