MAX4428CSA+

Overview

The MAX4428CSA+ 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 supports both CMOS and TTL logic inputs. The device provides independent inverting and non-inverting outputs with peak currents of 1.5A for both sourcing and sinking. Packaged in an 8-pin SOIC, it is designed for driving N-channel and P-channel MOSFETs with typical rise and fall times of 20ns.

Feature Summary

• Dual channel configuration providing independent inverting and non-inverting outputs
• Capable of driving both N-channel and P-channel MOSFETs
• Supports standard CMOS and TTL logic input levels

Applications

• Low-side switching applications for power management circuits
• Gate drive interfaces for discrete MOSFETs in motor control systems
• General purpose digital isolation or buffering in industrial equipment

Procurement Notes

Verify the specific suffix 'CSA+' against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Ensure the operating temperature range aligns with system requirements. Check for any recent obsolescence notices or alternative part recommendations from Analog Devices due to product lifecycle changes.

Selection Notes

Select this component when a dual output gate driver with complementary polarity is required for low-side switching. It is suitable for applications needing moderate speed (20ns) and sufficient drive current (1.5A). Consider thermal dissipation in the SOIC package if continuous high-current operation is expected at elevated ambient temperatures.

Part Context

This device belongs to the MAX4426-28 series of gate drivers from Maxim Integrated. It serves as a solution for efficiently controlling power switches in compact designs. The SOIC package allows for surface-mount assembly, facilitating integration into space-constrained printed circuit boards for consumer and industrial electronics.

Replacement Considerations

Consult the official MAX4426-28 datasheet for pin-compatible alternatives or updated revisions. Verify electrical parameters such as propagation delay and output current capability against potential substitute parts to ensure functional equivalence in the existing circuit design.
