MAX627MJA/883B

Overview

The MAX627MJA/883B is a dual low-side gate driver designed for Dual-Power MOSFET applications. It operates within a supply voltage range of 4.5 V to an unspecified maximum, with a typical operating current of 8 mA. The device features symmetric switching characteristics, providing rise and fall times of 30 ns each. It supports CMOS and TTL logic inputs and dissipates up to 640 mW of power. The component functions reliably across an extended temperature range from -55°C to +125°C and is housed in a CERDIP-8 package.

Feature Summary

• Dual-channel output configuration for independent low-side MOSFET control
• Compatible with standard CMOS and TTL logic input levels
• Symmetric 30 ns rise and fall times for precise switching timing
• Extended industrial temperature rating for harsh environment operation

Applications

• Driving dual low-side Power MOSFETs in power conversion circuits
• Industrial motor control systems requiring isolated or robust gate drive
• High-reliability aerospace or military electronic assemblies

Procurement Notes

Verify the specific suffix /883B indicates Mil-Spec qualification requirements before procurement. Confirm availability status as limited supply or factory special order may apply. Ensure the CERDIP-8 through-hole package aligns with the target PCB layout. Validate that the 4.5 V minimum supply voltage meets system design margins. Check RoHS compliance status if environmental regulations are mandatory for the end application.

Selection Notes

Select this component when dual low-side driving capability is required with high-speed switching performance. The 30 ns transition time suits applications demanding fast MOSFET turn-on and turn-off. Verify that the 8 mA operating current fits within the system's power budget. Ensure the logic interface matches existing CMOS or TTL control signals. Consider the thermal dissipation limits of 640 mW for the intended enclosure environment.
