brush DC-motors (e.g., cameras and disk drive head positioners).

pump, with independent control of each H-Bridge via parallel MCU

interface. The device features built-in shoot-through current

protection and an undervoltage shutdown function.

and Tri-Stated (High Impedance). The 17531A has a low total

power dissipation owing to its low output resistance and high output

slew rates. The H-Bridge outputs can be independently pulse width

modulated (PWM’ed) at up to 200 kHz for speed/torque and current

control.
