´╗┐Toshiba Europe Electronics Corporation introduces a dual-channel solenoid driver IC that provides a high-voltage driver with low on-resistance. The new TB67S112PG driver IC is ideal for a variety of applications, including household appliances (air conditioners and refrigerators), industrial equipment (bank terminals such as ATMs, office automation equipment, and factory automation equipment). The company's solenoid driver IC family currently includes four- and eight-channel devices (TB67S111PG and TB67S158NG / FTG). The new devices complement the product lineup by supporting dual-channel applications at a more economical price. The new device includes two channels, each of which consists of a low-side MOSFET and a renewable common diode that can independently drive solenoids or relays up to 50V. A low on-resistance of only 0.3Ohm provides higher output voltage, generates higher motor torque, and reduces heat generated during motor operation. By providing overcurrent detection (ISD), UVLO detection and TSD, safe operation can be facilitated, and a flag is also set to notify the system controller of a thermal shutdown event.
