Irvine, Calif.—Stressing high efficiency, Toshiba's three high-voltage, three-phase motor driver ICs include comprehensive power management circuitry for DC brushless motors, air conditioner fans, and pump motors.
The PWM drivers, using a high-voltage silicon on insulator (SOI) trench isolation process for a high level of integration, include the TPD4111K (rated at 250 volts and 1 amp); TPD4112K (500 volts, 1 amp); and the TPD4104K (500 volts, 2 amps). They feature a Hall amp, three-phase full-bridge distribution circuit with level-shift type high-side driver and low-side driver, fast recovery diode (FRD), boostrap diodes to eliminate the need for a high-side power supply, 6- or 7-volt regulator, and IGBT output. The ICs include over-current, under-voltage and thermal-shutdown protection.
