Toshiba launches high-voltage, dual-channel solenoid driver IC
Published: 26 September 2019 - Christian Lynn
Toshiba Electronics Europe GmbH has launched a dual-channel solenoid driver IC that provides a high-voltage drive, with low ON resistance. Dubbed the 'TB67S112PG', this product is suited to applications ranging from domestic appliances (air-conditioners and refrigerators) to industrial equipment (banking terminals such as ATMs and office/factory automation equipment).
Toshiba’s solenoid driver IC lineup currently includes four- and eight-channel devices (TB67S111PG and TB67S158NG/FTG). The new TB67S112PG completes the lineup, by providing support for dual-channel applications at a lower price point.
The new 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 0.3O 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.
