MAX628CSA+T

Overview

The MAX628CSA+T is a dual power MOSFET driver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5 V to 18 V and supports data rates up to 10 Mb/s. The device features a typical rise time of 25 ns and fall time of 20 ns, with output currents of 2 A for both high-side and low-side drivers. It functions in an extended temperature range from -40°C to +85°C and consumes 600 µA of operating current. Packaged in an 8-pin SOIC (SO-8) surface-mount format, it dissipates approximately 471 mW of power.

Feature Summary

• Translates TTL-compatible inputs into high-current, high-voltage outputs for efficient MOSFET switching
• Provides independent high-side and low-side drive channels with symmetrical rise and fall times
• Incorporates fail-safe logic to maintain stable outputs during input signal loss or undefined states

Applications

• Synchronous rectification in DC-DC converters
• Half-bridge and full-bridge gate drive circuits
• Motor control applications requiring fast switching transitions

Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc. or Maxim Integrated, as branding may vary across production lots. Ensure the component matches the SO-8 package dimensions and pinout configuration required by your PCB layout. Cross-reference the datasheet revision date to confirm compatibility with your design specifications.

Selection Notes

Select this component for designs requiring robust dual-channel MOSFET driving with integrated fail-safe functionality. It is suitable for applications needing precise timing control with low propagation delay variations. Consider the thermal dissipation capabilities relative to the expected duty cycle and ambient temperature conditions. Verify that the input logic levels are compatible with the controlling microcontroller or FPGA signals.

Part Context

This part belongs to the MAX628 series of dual power MOSFET drivers. It is functionally related to the MAX626 and MAX627 variants, which offer similar drive capabilities but may differ in specific electrical characteristics or package options. The series is designed for high-efficiency power conversion systems where reliable switching performance is critical.

Replacement Considerations

Publicly confirmed substitute part numbers include MAX628CSA+. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Note that the MAX628CSA variant is obsolete; ensure any replacement maintains the same functional integrity and package footprint.
