Toshiba Launches High-Voltage Dual-Channel Solenoid Driver IC

October 7, 2019 Alix Paultre

Toshiba Electronics Europe launched the TB67S112PG dual-channel solenoid driver IC with a high-voltage drive offering low ON resistance. The IC lineup currently includes 4- and 8-channel devices, with the TB67S112PG providing support for dual-channel applications at a lower price point. The two channels, each consisting of a low-side MOSFET and a regenerative common diode, can independently drive a solenoid or relay at voltages up to 50V.

An ON resistance of 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.
