0.7 A dual H-Bridge motor driver with 3.0 V/5.0 V 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 HBridge via parallel MCU interface (3.0 V and 5.0 V compatible logic). The device features an on-board charge pump, as well as built-in shoot-through current protection and an under
voltage 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 at 25 °C). The 17529’s low output resistance and high slew rate provides efficient drive for many types of micromotors.
Features Low total RDS(on) 0.7 Ω (typ), 1.2 Ω (max) at 25 °C Output current 0.7 A (DC), 1.4 A (peak) Shoot-through current protection circuit 3.0 V/5.0 V
CMOS-compatible inputs PWM control input frequency up to 200 kHz Built-in charge pump circuit Low power consumption Under
voltage detection and shutdown circuit
