THEMIS Power Transistor Driver Controller

CHT-THEMIS controls the CHT-ATLAS power transistor driver chipset for SiC, GaN and silicon power devices. One controller can manage up to five ATLAS ICs for a gate-drive solution delivering up to ±20 A.

A control and fault-management state machine works with adjustable undervoltage lockout, desaturation detection and active Miller clamping through an external transistor. An integrated 5 V regulator supplies the driver logic and compatible external circuitry.
