electronic applications to control bipolar step motors and
brush DC motors such as those found in camera lens
assemblies, camera shutters, optical disk drives, etc. The
17529 operates from 2.0 V to 6.8 V, providing dual H-bridge
motor drivers with parallel 3.0 V- or 5.0 V-compatible I/O. The
device features an on-board charge pump, as well as built-in
shoot-through current protection and undervoltage
shutdown.

undervoltage threshold. If the supply voltage drops below the
undervoltage threshold, the output power stage switches to a
tri-state condition. When the supply voltage returns to a level
that is above the threshold, the power stage automatically
resumes normal operation according to the established
condition of the input terminals.
LOGIC INPUT CONTROL (IN1A, IN1B, IN2A, AND
IN2B)
IN1A logic HIGH = OUT1A HIGH. However, if all inputs are
taken HIGH, the outputs bridges are both tri-stated (refer to

becomes controlled and/or modulated by the IC as it delivers
the power to the loads attached between the output
terminals. All VM terminals must be connected together on
