FAN7387VN

Overview

The FAN7387VN is a half-bridge gate driver IC manufactured by onsemi, formerly Fairchild Semiconductor. It features two drivers in a DIP-8 package for through-hole mounting. The device supports a supply voltage range of 11 V to 14 V and delivers an output current of 25 mA. Electrical characteristics include a rise time of 120 ns and a fall time of 70 ns. It operates within a temperature range of -40°C to +125°C with a power dissipation of 1.2 W.

Feature Summary

• Provides high-side and low-side gate drive capabilities for half-bridge configurations.
• Designed for driving MOSFETs and IGBTs in power conversion applications.
• Features robust thermal performance suitable for industrial environments.

Applications

• High-voltage power supply designs
• Industrial motor control systems
• Lighting ballast controllers

Procurement Notes

Verify the manufacturer origin as onsemi, noting the historical Fairchild Semiconductor branding. Confirm the specific suffix 'VN' corresponds to the DIP-8 through-hole package variant. Check datasheet revisions for any changes in pinout or electrical specifications compared to earlier iterations. Ensure compliance with RoHS standards if required by the target application regulations.

Selection Notes

Select this component when a through-hole half-bridge driver is required for lower power applications due to its 25 mA output capability. Compare against surface-mount variants like the FAN7387MX if PCB space constraints differ. Evaluate the 1.2 W power dissipation limit against the expected thermal load in the final assembly to ensure reliable operation within the specified temperature range.

Part Context

The FAN7387 series belongs to the family of IGBT and MOSFET gate drivers from onsemi. This specific part represents the legacy Fairchild product line now managed under the onsemi portfolio. It serves as a specialized solution for driving power switches in applications requiring isolated or non-isolated half-bridge topologies with moderate current demands.
