This “Inverter Power H-IC” is highly integrated device containing all High Voltage HV control from HV-DC to 3-phase outputs in a single SIP module Single-In Line Package. Output stage uses IGBT/FRB technology and implements Under Voltage Protection UVP and Over Current Protection OCP with a Faults Detection output flag. Internal Boost diodes are provided for high side gate boost drive.

**Function:**

* Single control power supply due to Internal bootstrap circuit for high side pre-driver circuit

* All control input and status output are at low voltage levels directly compatible with microcontrollers

* Built-in dead time for shoot-thru protection

* External accessible embedded thermistor for substrate temperature measurement

* The level of the over-current protection current is adjustable with the external resistor, “RSD”
