MAX4428CSA

Overview

The MAX4428CSA is a low-side gate driver IC manufactured by Analog Devices Inc./Maxim Integrated. It features dual independent channels with inverting and non-inverting inputs, designed for driving N-channel and P-channel MOSFETs. The device operates within a supply voltage range of 4.5V to 18V. It provides peak output currents of 1.5A for both sourcing and sinking. Typical rise and fall times are 20ns. Logic input thresholds are defined at 0.8V (VIL) and 2.4V (VIH). The component is housed in an 8-SOIC package.

Feature Summary

• Dual independent low-side gate driver configuration supporting both inverting and non-inverting logic inputs.
• Capable of delivering 1.5A peak source and sink current for efficient MOSFET switching.
• Operates with a wide supply voltage range from 4.5V to 18V.
• Features fast switching characteristics with typical 20ns rise and fall times.

Applications

• Driving N-channel and P-channel power MOSFETs in low-side configurations
• General-purpose gate drive applications requiring high peak current
• Power management circuits utilizing low-side switching topologies

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature rating. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure the supplier provides valid manufacturer documentation for quality assurance. Check for RoHS compliance requirements if applicable to your assembly process. Validate pinout compatibility with existing PCB layouts before procurement.

Selection Notes

Select this component when a low-side driver with dual independent channels is required. Consider the 1.5A peak current capability for driving moderate-capacitance loads. Verify that the operating supply voltage range of 4.5V to 18V matches the system design. Ensure the 8-SOIC package fits the available board space. Evaluate the 20ns switching speed against the required frequency of operation.

Part Context

The MAX4428 belongs to a family of low-side gate drivers from Maxim Integrated. It is functionally similar to other devices in the series but distinguished by its specific package and electrical ratings. The CSA variant denotes the commercial temperature range and SOIC packaging. This part serves as a discrete solution for controlling power switches in various electronic systems.

Replacement Considerations

Check for direct pin-to-pin replacements such as the MAX4428CSA+T. Verify that any substitute maintains the same 1.5A peak current and 4.5V-18V supply range. Ensure the replacement supports both inverting and non-inverting inputs. Confirm package compatibility with the existing footprint.
