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
DS(ON)
of 1.2
鈩?/div>
(max
@ 25擄C).
The 17529鈥檚 low output resistance and high slew rates provide efficient
drive for many types of micromotors.
