Optocoupler - ICPL-316J

The ICPL-316J is a highly integrated power control device that integrates all necessary components of a complete, isolated IGBT gate drive circuit, along with fault protection and feedback, into an SOP-16 package.

TTL input logic levels allow direct interface with microcontrollers. The optically isolated power output stage drives IGBTs rated up to 150 A and 1200 V. The output IC provides local protection for the IGBT against damage during overcurrent conditions, and a second optical link provides a fully isolated fault status feedback signal to the microcontroller. A built-in 'watchdog' circuit monitors the power stage supply voltage to prevent undervoltage gate drive that could damage the IGBT. This integrated IGBT gate driver is designed to improve the performance and reliability of motor drives.
