TIDA-00448, Flexible High Current IGBT Gate Driver with Reinforced Digital Isolator Reference Design

TIDA-00448, Flexible High Current IGBT Gate Driver with Reinforced Digital Isolator Reference Design. The TIDA-00448 reference design is an isolated IGBT gate driver with bipolar gate voltages intended for driving high power IGBT requiring high peak gate current up to 40A. NexFET power blocks which scales in this range, with same package, enables single design to be used for multiple drive platforms with different power ratings. A Digital isolator is used to achieve reinforced isolation with transient surge rating of 8kV and 50kV CMTI. The design incorporates DESAT protection using a fast transient response comparator. The DESAT detection threshold and the soft turn-off time are configurable. The design can interface with PWMs from 3.3V and 5V MCUs along with fault, reset and UVLO feedbacks
