STK531U394A-E

This “Inverter IPM” 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/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.

• Protective circuits including over current (bus line) and pre-drive low voltage protection are built in.
• Direct input of CMOS level control signals without insulating circuits is possible. (Active HIGH)
• A single power supply drive is enabled through the use of bootstrap circuits for upper power supplies. (externally set)
• Built-in simultaneous upper/lower ON prevention circuit to prevent arm shorting through simultaneous ON input for the upper and lower side transistors.
  (Dead time is required for preventing shorting due to switching delay.)
• The level of the overcurrent protection current can be changed with the external resistor “RSD” between the “ISD” and “VSS” terminals.
• Monitoring substrate temperature is possible through the use of an internal thermistor.
• Certification : UL Recognized (File number : E339285)
