MP18831-A4BGY-Z

Isolators - Gate Drivers Overview

The MP18831-A4BGY-Z is a galvanically isolated half-bridge gate driver manufactured by Monolithic Power Systems. It utilizes capacitive coupling technology to provide signal isolation with a rated isolation voltage of 5000 Vrms. The device features dual inputs and drives both high-side and low-side outputs, delivering up to 4A of source and sink peak current. It operates within a temperature range of -40°C to +125°C and is housed in a 16-SOIC package.

Isolators - Gate Drivers Feature Summary

• Galvanic isolation via capacitive coupling for robust noise immunity
• Dual-input control architecture supporting half-bridge configurations
• High peak output current capability for efficient power switch driving

Isolators - Gate Drivers Applications

• Isolated DC-DC converter designs
• Motor drive systems requiring high-side and low-side control
• Industrial power supply applications

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'Z' against official MPS documentation to confirm compliance status and tape-and-reel packaging details. Ensure the selected variant matches the required isolation voltage and operating temperature specifications for the target application environment before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when high common-mode transient immunity and reliable galvanic isolation are required in compact designs. The 4A output current supports medium-power switching applications. Confirm that the 16-SOIC footprint fits the PCB layout constraints and that the input logic levels are compatible with the control circuitry.

Isolators - Gate Drivers Part Context

This part belongs to the MP18831 family of isolated gate drivers from Monolithic Power Systems. The series offers various isolation technologies and pinout options. The A4BGY-Z designation specifies the capacitive coupling variant with specific thermal and mechanical characteristics distinct from other family members like the optical isolation versions.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include the MP18831-A4BGSE-P, which offers similar functionality but uses optical isolation instead of capacitive coupling. Verify pin compatibility and isolation voltage ratings when considering alternative packages or isolation methods within the same product line.
