TB67S112PG
TOSHIBA BiCD Process Integrated Circuit Silicon Monolithic TB67S112PG
Parallel controlled solenoid driver
The TB67S112PG is a solenoid driver for parallel input.
Using the BiCD process, the output voltage of 50 V, and the output current of
1.5 A/ch (absolute maximum rating) are realized. Weight: 1.11 g (typ.) Features
・ BiCD integrated circuit silicon monolithic. ・ Capable of driving up to two solenoids simultaneously. (2-ch sink driver) ・ Capable of driving a unipolar stepping motor with two chips. ・ Built-in over current detection (automatic return / time control) at each output. ・ Built-in thermal shutdown detection (automatic return / time control), which detects errors of the whole device. ・ Built-in output MOSFET for low ON resistance (0.3 Ω (typ.). ・ High voltage and large current (Refer to “Absolute maximum ratings” and “Operating range”.). ・ Built-in various error detection functions (Thermal shutdown (TSD), over current detection (ISD), and Under voltage
lockout(UVLO)

Some of the functional blocks, circuits, or constants in the block diagram may be omitted or simplified for explanatory
purposes. IC considerations
When using TB67S112PG, the GND pattern of PCB should be a solid pattern and be externally terminated at only one
point. Also, a grounding method should be considered for efficient heat dissipation.
Careful attention should be paid to the layout of the output, VM, COM, and GND traces, to avoid short circuits across …
