FAN7023MU

Overview

The FAN7023MU is a high-speed, half-bridge MOSFET gate driver manufactured by Fairchild Semiconductor. It integrates two independent outputs configured for high-side and low-side driving applications. The device operates with a supply voltage range of 10 V to 20 V and delivers a peak output current of 2 A. It features a fixed internal delay time to ensure proper timing control between the high-side and low-side switches. The component is housed in an 8-pin MSOP surface-mount package.

Feature Summary

• Integrated half-bridge configuration for driving high-side and low-side power MOSFETs
• High-speed operation with specified propagation delays for switching control
• Built-in shoot-through protection mechanism to prevent simultaneous conduction

Applications

• Motor drive systems requiring half-bridge topology
• DC-DC converter circuits utilizing synchronous rectification
• Power supply designs necessitating isolated or non-isolated gate driving

Procurement Notes

Verify the manufacturer designation as Fairchild Semiconductor, noting that onsemi is the successor entity. Confirm the specific suffix 'MU' corresponds to the MSOP-8 package variant. Ensure compliance with RoHS directives if required by the application environment. Cross-reference the datasheet revision date to confirm parameter stability before finalizing procurement specifications.

Selection Notes

Select this component when a single-chip solution for half-bridge driving is required within a 10 V to 20 V supply range. The 2 A peak current capability suits medium-power MOSFET applications. Consider the MSOP-8 package constraints for PCB layout space. Verify that the internal dead-time and propagation delay characteristics align with the target switching frequency requirements.

Part Context

This part belongs to the FAN702x series of half-bridge gate drivers. These devices are designed to simplify the design of power conversion stages by integrating necessary logic and protection features into a compact package. The series typically offers variations in package types and electrical characteristics to suit different thermal and spatial constraints in power electronics designs.

Replacement Considerations

Check for equivalents from onsemi, the successor to Fairchild Semiconductor. Other manufacturers offering similar half-bridge drivers with comparable voltage ranges and output currents may serve as alternatives. Ensure pin compatibility and electrical parameters match before substituting.
