Toshiba launches high-voltage dual-channel solenoid driver IC

Toshiba Electronics Europe has launched a dual-channel solenoid driver IC that provides a high-voltage drive with low ON resistance.

The TB67S112PG driver IC is suited to a wide variety of applications including domestic appliances (air-conditioners and refrigerators), industrial equipment (banking terminals such as ATMs, office automation equipment, and factory automation equipment).

Toshiba’s solenoid driver IC line-up currently includes 4- and 8-channel devices (TB67S111PG and TB67S158NG/FTG). The TB67S112PG completes this line-up, by providing support for dual-channel applications at a lower price point.

The device incorporates two channels, each consisting of a low-side MOSFET and a regenerative common diode that can independently drive a solenoid or relay at voltages up to 50V. A low ON resistance of only 0.3Ω allows for a higher output voltage, resulting in higher motor torque, and reducing heat generation during motor operation.

Safe operation is enabled through the provision of overcurrent detection (ISD), under voltage lockout (UVLO) detection and thermal shutdown detection (TSD), which, additionally, sets a flag to notify the system controller of a thermal shutdown event.

Mass production of the TB67S112PG has already begun.
