NXP Semiconductors Technical Data 700 mA dual H-Bridge motor driver with 3.
0 V compatible logic I/O 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).
The 17531A operates from 2.
0 to 8.
6 V using the internal charge pump, with independent control of each H-Bridge, via a 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-state (high-impedance).
The 17531A has a low total RDS(on) of 1.
2 Ω (max at 25 °C).
