Technical Data

Configurable Motor Driver IC

with Power Supplies

34921

The 34921 power IC integrates multiple motor drivers, multiple

power regulators, and most other analog functions a small consumer

motion-enabled product needs. The 34921’s circuitry is fully protected

with current limiting, short-circuit shutdown, over-temperature, over-

voltage, and under-voltage detection. Supervisory functions can be

read and programmed through a 8-MHz Serial Interface.

H-BRIDGE MOTOR DRIVER

AND POWER SUPPLY

A 5.0 V dual-mode (linear or switching) voltage regulator, 3.3 V

switching buck regulator, and a voltage-selectable (1.5 V, 1.8 V, 2.5 V)

linear regulator provide power management. Two H-Bridges and a

configurable motor driver are provided for controlling two dc motors

and one unipolar stepper motor.

The highly integrated 34921 brings together sensing,

communication, power management, system protection, and motor

control in one device.
