0.7 A Dual H-Bridge Motor Driver with 3.0V/5.0V Compatible Logic I/O

The 17529 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 17529 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 on-board charge pump, as well as built-in shoot-through current protection and an undervoltage shutdown function.

The 17529 has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance). The 17529 has a low total RDS(ON) of 1.2 Ω (max @ 25°C).

The 17529’s low output resistance and high slew rates provide efficient drive for many types of micromotors.
