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 0.25Î©. 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 (0.25Î©) 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 (0.25Î©).
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.
