80V Multi-Channel Solenoid and Unipolar Motor Driver IC

April 17, 2017

Toshiba Corporation's today announced the launch of the TB67S111PG, a multi-channel solenoid and a unipolar motor driver IC that achieves high-voltage and low ON resistance drive. Sample shipments start today, with mass production scheduled to start in May.

TB67S111PG incorporates four channels of each low-side MOSFET and regenerative common diode. This enables it to control all output MOSFETs independently and realizes a design that is suited to driving the solenoids and unipolar motors widely used in such applications as amusement equipment (pachinko and slot machines), home appliances (air-conditioners and refrigerators) and industrial equipment (vending machines, banking terminals such as ATMs, office automation equipment and factory automation equipment).

Fabricated with the latest high-voltage analog power process, BiCD 130nm, the motor driver IC achieves an output rating of 80V and reduces IC heat generation by lowering the output ON resistance to 0.25Ω. The IC is packaged in a high heat dissipation H-frame DIP package that can be mounted on low-cost paper phenol board and on a general glass-epoxy board. Main features include:

1. Four channels of each low-side MOSFET and regenerative common diode; allows all output MOSFETs to be controlled independently. The IC is suited to multi-channel solenoid drives and unipolar motor drives.

2. High voltage (80V) and low ON resistance (0.25Ω) drive; High-voltage (80V) MOSFET in the output block provides support for solenoid and unipolar motor drives. Heat generation during motor operation can be reduced by low ON resistance (0.25Ω).

3. Lead insert type package (DIP); The H-frame DIP package, which has high heat dissipation, supports diverse consumer and industrial applications.

4. Built-in error detections with automatic reset functions; A thermal shutdown circuit and overcurrent shutdown circuit protect the IC when abnormalities occur in set usage, and automatically reset IC operation after a specified time.
