TOSHIBA ANNOUNCES HIGH VOLTAGE THREE-PHASE MOTOR DRIVERS WITH BUILT-IN POWER MANAGEMENT CIRCUITS FOR ENERGY-SAVING IN APPLIANCE AND MACHINERY APPLICATIONS
Toshiba America Electronic Components, Inc. has announced three high-voltage three-phase motor drivers with built-in power management (PWM) circuits for direct current (DC) brushless motors, air conditioner fans, and pump motors. Developed by Toshiba Corp. (Toshiba), the TPD4104K, TPD4111K and TPD4112K single chip inverter ICs are manufactured using a high voltage silicon on insulator (SOI) trench isolation process to achieve this level of integration.
250V and 500V Single Chip PWM Drivers for DC Brushless Motors Feature a High Level of Integration to Reduce Board Space and Power Consumption
The three devices provide a range of voltage and current specifications to meet varying customer requirements.The TPD4111K is rated for 250 volts (V) with direct current (DC) output of 1 ampere (Amp), the TPD4112K is a 500V rated device with DC output of 1 Amp, and the TPD4104K is a 500V rated device with DC output of 2 Amps.
In addition to the power management capability, the new motor drivers feature a three-phase full-bridge distribution circuit with level-shift type high-side driver and low-side driver, output insulated gate bipolar transistor (IGBT), and built-in fast recovery diode (FRD).
