MAX4426CPA+

Overview

The MAX4426CPA+ is a dual low-side MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5V to 18V and delivers an output current of 1.5A per channel. The device features inverting logic compatible with CMOS and TTL inputs, with rise and fall times of 25ns. It is housed in an 8-pin PDIP package and supports through-hole mounting.

Feature Summary

• Dual-channel configuration for independent low-side switching control
• Inverting input logic compatible with standard digital interfaces
• High-speed switching capability with symmetric 25ns transition times

Applications

• Low-side MOSFET driving in power management circuits
• Motor control applications requiring dual channel isolation
• General-purpose switching power supplies

Procurement Notes

Verify the specific suffix 'CPA+' against the manufacturer's latest documentation to confirm pinout and electrical specifications. Ensure the procurement source provides valid traceability for this Analog Devices component. Confirm that the 8-pin DIP package matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when dual low-side drive is required with moderate current capabilities. The inverting logic simplifies interface design with common microcontrollers. Verify that the 18V maximum supply voltage aligns with the system's power rails. Consider the PDIP package constraints for high-density board layouts.

Part Context

This part belongs to the Maxim Integrated gate driver family, designed for reliable MOSFET switching. It serves as a bridge between low-power logic controllers and higher-power semiconductor switches. The dual-channel architecture allows for synchronized or independent control of two external N-channel MOSFETs in compact systems.

Replacement Considerations

The TC4426CPA from Microchip Technology offers similar dual-channel low-side driving capabilities with comparable current ratings and packaging.
