Toshiba offer a wide range of general purpose linear ICs
including power supply ICs, intelligent power devices, motor
drivers, operational amplifier ICs & comparator ICs, interface
drivers and small signal MMICs.

Intelligent Power Devices & Single Chip Inverter ICs
High Voltage Intelligent Power Devices (HV-IPD)
or Single Chip Inverter ICs are the easiest way to "Brushless DC
Motor Drive". Only few external passive components are necessary
to realize a full operating motor control. The resulting system
can directly operate from the 240VAC, because the maximum
voltage rating of the device is 500V.
This HV-IPD is called Single Chip Inverter IC, because there is
REALLY 1 chip inside the package. The following protections are
integrated inside the chip: overheating protection, under
voltage protection and over current limitation.
The line-up encompasses 9 devices
divided into 2 groups of available products:
-
8 items able to generate a 'Sine Wave Output current'. These
devices have no PWM on board. They can be driven, e.g. with a
compatible TOSHIBA's TB6551
sine wave control IC or with a
TMPM370 vector control MCU for sensorless operation.
Also other MCUs could be applied With that configuration the noise of
motor can be drastically reduced. The following current ratings
are available: 1A, 2A and 3A. Same pin layout of all items allows easy
exchange in case of different motor power ratings. All those item
are optionally available with our without over current protection.
-
There are
2 items generating a 'Rectangular Wave Output Current'. These
devices have PWM on board. This is stand-alone concept, means no
additional control IC or MCU are necessary to drive the motor. Just a
simple potentiometer and a low voltage power supply are necessary to
control the motor. For cost reduction purpose, 3 op-amplifiers are
integrated into the Chip, so inexpensive hall sensors can be used
instead of hall ICs.
