STK621-210B

OUTLINE ・This IC is a 3-phase inverter power hybrid IC containing power elements (IGBT and

FRD), pre-driver, overcurrent protection circuit.

APPLICATION ・3-phase inverter motor drive

FEATURES ・Integrates power elements (IGBT and FRD), pre-driver, and protective circuit.

・Protective circuits including overcurrent (bus line), and pre-drive low voltage

protection are built in.

・Direct input of CMOS level control signals without an insulating circuit

(photocoupler, etc) is possible.

･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.)

･SIP (The single in-line package) of the transfer full mold structure.
