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.
3-phase inverter motor drive 450V-600V,+-8A
