Toshiba: high-voltage multi-channel solenoid and unipolar motor driver IC
Toshiba Electronics Europe launch a multi-channel solenoid and unipolar motor driver IC that delivers high-voltage and low ON resistance drive. TB67S111PG incorporates four channels each consisting of one low-side MOSFET and a free-wheeling diode connected to drain. This enables it to control each channel independently and realises a design that is suited to driving the solenoids and unipolar motors that are widely used in applications such as slot machines and home appliances (refrigerators), industrial equipment (vending machines, banking terminals, ATMs) and office and factory automation equipment. Fabricated with the latest high-voltage analog power process (BiCD 130nm), the motor driver IC offers an output rating of 80V at 1.5A per channel. Power dissipation is minimised by an output ON resistance of 0.25Ω.
Thermal and overcurrent shutdown circuits protect and automatically reset IC operation after a specified time. There is also a built-in thermal shutdown flag output. The device supports power-on sequencing for a single power drive. The IC is packaged in a thermally dissipative H-frame DIP16-P-300-2.54A package that can be mounted on low-cost paper phenol board and on a general glass-epoxy board.
