0.7 A 6.8 V Dual H-Bridge Motor Driver
17533
The 17533 is a monolithic dual H-Bridge power IC ideal for portable electronic applications containing bipolar stepper motors and/or brush DC-motors (e.g., cameras and disk drive head positioners).
The 17533 operates from 2.0 V to 6.8 V, with independent control of each H-Bridge via parallel MCU interface (3.0 V and 5.0 V compatible logic). The device features built-in shoot-through current protection and an undervoltage shutdown function.
The 17533 has four operating modes: forward, reverse, brake, and tri-stated (high-impedance). The 17533 has a low total RDS(ON) of 1.2 Ω (max at 25 °C).
