HCPL-314J#500

Isolators - Gate Drivers Overview

The HCPL-314J#500 is a dual-channel high-speed gate drive optocoupler from Broadcom Limited. It integrates an AlGaAs LED with an integrated circuit featuring a power output stage, designed for driving IGBTs and MOSFETs. Key electrical parameters include a minimum peak output current of 0.4A per channel, a maximum propagation delay of 0.7µs, and a common-mode rejection ratio (CMR) of at least 10 kV/µs at Vcm = 1.5kV. The device operates within a supply voltage range of 10V to 30V and supports a working temperature range from -40°C to +100°C. It provides 3750 Vrms isolation voltage and is housed in a 16-SOIC package.

Isolators - Gate Drivers Feature Summary

• Dual-channel architecture integrating AlGaAs LEDs with dedicated power output stages for simultaneous gate drive applications
• High common-mode immunity ensuring reliable signal transmission in noisy industrial environments
• Wide operating supply voltage range accommodating various gate driver requirements without external level shifting
• Comprehensive safety certifications including UL, CSA, and IEC standards for global compliance

Isolators - Gate Drivers Applications

• Isolated gate driving for IGBTs and power MOSFETs in motor control systems
• Inverter circuits for AC drives and brushless DC motor controllers
• Industrial frequency converters and variable speed drives
• Switched-mode power supplies requiring high isolation barriers
• Uninterruptible power supply (UPS) systems

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix '#500' confirms the reel packaging format when sourcing. Ensure the component matches the 16-SOIC footprint dimensions precisely during PCB layout validation. Confirm RoHS compliance status through official manufacturer documentation prior to assembly. Cross-reference the datasheet revision date to ensure compatibility with existing design specifications and regulatory requirements.

Isolators - Gate Drivers Selection Notes

Select this component when dual-channel isolation is required for synchronous switching applications. The 0.4A output current capability suits low-to-medium power IGBTs directly. Consider the 16-SOIC package for space-constrained designs compared to DIP alternatives. Evaluate the 10 kV/µs CMR against the expected noise levels in the target power circuit to ensure signal integrity.

Isolators - Gate Drivers Part Context

This part belongs to the HCPL-314J family of gate drive optocouplers manufactured by Broadcom Limited. The series is engineered specifically for power electronics applications demanding high-speed switching and robust isolation. The #500 designation typically indicates tape-and-reel packaging for automated assembly processes, distinguishing it from tube-packaged variants like the standard HCPL-314J.
