0.7 A 6.8 V Dual H-Bridge Motor
Driver
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 R
DS(ON)
of 1.2 Ω (max @ 25°C).
The 17533’s low output resistan ce and high slew rates provide
efficient drive for many types of micromotors.
