Logic I/O

17531A

The 17531A is a monolithic dual H-Bridge power IC ideal for

portable electronic applications containing bipolar step motors and/or

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

DUAL H-BRIDGE

The 17531A operates from 2.0 V to 8.6 V using the internal charge

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.

The 17531A has four operating modes: Forward, Reverse, Brake,

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

R_DS(ON)of 1.2 Ω (max @ 25°C).

The 17531A efficiently drives many types of micromotors with low

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.
