600V Intelligent Power Motor Drive with 5A Rating

Toshiba Corporation's Storage & Electronic Devices Solutions Company today announced the launch of the TPD4207F, the latest addition to its line-up of high voltage intelligent power devices (IPDs) in small-size packages for use in fan motors, including those of air conditioners, air cleaners and pumps. The new IPD is housed in a small SOP30 surface-mount package, and achieves an increased current rating of 5A and high voltage of 600V. Mass production shipments start today.

Utilizing Toshiba's latest MOSFET technology for reducing power loss, the 600V Super Junction MOSFET “DTMOSIV series,” the new IPD achieves a 5A rating. This is sufficient to drive the compressor motor of a refrigerator, which current IPDs cannot do, and will expand the range of application.

The TPD4207F is a dc brushless motor driver using high-voltage pwm control. It is fabricated by high voltage MOSFET (600V). It is three-shunt resistor circuit for current sensing. It contains level shift high-side driver, low-side driver, MOSFET outputs, and protective functions for over-current circuit and shutdown function and under voltage protection circuits and thermal shutdown circuit. It is easy to control a DC brush less motor by just putting logic inputs from a MPU or motor controller to the TPD4207F.

Features include: High voltage power side and low voltage signal side terminal are separated. It is the best for current sensing in three shunt resistance. Bootstrap circuit gives simple high-side supply. Bootstrap diodes are built in. A dead time can be set as a minimum of 1.4 μs, and it is suitable for a Sine-wave drive. 3-phase bridge output using MOSFETs. Includes over-current and under-voltage protection and shutdown and thermal shutdown. And a 7V regulator is built in.
