Overview

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 DIP module (Dual-In line Package). Output stage uses IGBT/FRD technology and implements Under Voltage Protection (UVP) and Over Current Protection (OCP) with a Fault 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 inputs and status outputs are at low voltage levels directly compatible with microcontrollers.

• A single power supply drive is enabled through the use of bootstrap circuits for upper power supplies

• Built-in dead-time for shoot-thru protection

• Having open emitter output for low side IGBTs; individual shunt resistor per phase for OCP

• Externally accessible embedded thermistor for substrate temperature measurement

• Shutdown function ‘ITRIP’ to disable all operations of the 6 phase output stage by external input
