17531A

Overview
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).
The 17531A efficiently drives many types of micromotors with low power dissipation owing to its low output resistance and high output slew rates.
The HBridge outputs can be independently pulse width modulated (PWM’ed) at up to 200 kHz for speed/torque and current control.
This device is powered by SMARTMOS technology.
Features • Low total RDS(on) 0.
8 Ω (Typ), 1.
2 Ω (Max) at 25 °C • Output current 0.
7 A (DC) • Shoot-through current protection circuit • PWM control input frequency up to 200 kHz • Built-in charge pump circuit • Low power consumption • Undervoltage detection and shutdown circuit • Power save mode with current draw ≤ 2.
