FAN7387N

Overview

The FAN7387N is a half-bridge gate driver IC manufactured by onsemi, designed for driving IGBTs and MOSFETs in high-voltage applications. It features a dual-channel output configuration housed in an 8-pin DIP package suitable for through-hole mounting. The device operates within a supply voltage range of 11 V to 14 V and supports a maximum power dissipation of 1.2 W. It provides peak output currents of 25 mA with rise and fall times of 120 ns and 70 ns, respectively. The component functions reliably across an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrated half-bridge topology supporting both high-side and low-side switching control
• Through-hole DIP-8 packaging for standard board mounting applications
• Built-in under-voltage lockout (UVLO) protection for both high and low sides
• External dead-time control capability to prevent shoot-through conditions

Applications

• Half-bridge inverter circuits
• Switched-mode power supplies (SMPS)
• Fluorescent lamp ballasts
• High-intensity discharge (HID) lamp drivers

Procurement Notes

Verify current availability status as the FAN7387N is listed as discontinued or obsolete in major distributor catalogs. Confirm lead times and end-of-life notices directly with onsemi or authorized agents. Ensure alternative sourcing channels are identified if production continuity is required. Check RoHS compliance documentation for specific manufacturing batches.

Selection Notes

Select this component when through-hole mounting is required for half-bridge gate drive applications. Compare against the surface-mount FAN7387MX variant if PCB space constraints favor SMD packages. Evaluate the lower output current and slower switching speeds relative to newer high-performance drivers. Verify that the 1.2 W power dissipation rating meets thermal requirements for the target application environment.

Part Context

The FAN7387N belongs to the FAN7387 series of self-oscillating high-voltage gate drivers. This family includes variants such as the FAN7387M and FAN7387MX, which offer similar functional characteristics but differ in packaging and mounting style. The series is engineered for cost-effective solutions in lighting and power conversion systems requiring reliable half-bridge operation.

Replacement Considerations

Consider the FAN7387MX as a direct pin-compatible alternative if surface-mount technology is acceptable. Verify electrical parameter compatibility regarding output current and switching speeds before substitution.
