TOSHIBA TB6524FN

TB6524FN
TOSHIBA Bi−CMOS INTEGRATED CIRCUIT SILICON MONOLITHIC
TB6524FN
DC MOTOR DUAL FULL BRIDGE DRIVER (H−SWITCH)
The TB6524FN is a bridge driver most suitable for switching
between normal rotation and reverse rotation and can control
three modes, normal rotation, reverse rotation, and stop.
The driver is capable of handling output current of 100 mA.
Fixed current operation is also available as the control method.

APPLICATION CIRCUIT
Note:
Utmost care is necessary in the design of the output line, VCC and GND line since IC may be destroyed due
to short−circuit between outputs, air contamination fault, or fault by improper grounding.
