Advance Information
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 R
@25°C).
The 17529’s low output resistance and high slew rates provide efficient
drive for many types of micromotors.
Features
• Low Total R
• 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
• Undervoltage Detection and Shutdown Circuit
• Pb-Free Packaging Designated by Suffix Code EV
0.7 Ω (Typ), 1.2 Ω (Max) @ 25°C
