Abstract
A galvanically isolated gate driver for a power transistor is disclosed. The gate driver provides various temperature protection features that are enabled by (i) diagnostic circuitry to generate fault signals and monitoring signals, (ii) signal processing to enable communication over a shared communication channel across an isolation barrier, (iii) signal processing to reduce operating current needed for real-time thermal monitoring, and (iv) a disable circuit for unused temperature sensing pins.
