Configurable Motor Driver IC
with Power Supplies
MC34921
Rev 5.0, 07/2005
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.
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.
Features
• Two Functionally Identical Pulse-Width Modulated (PWM) DC Motor
Drivers
• One Switching, One Linear, and One Dual-Mode Regulator
• Dual Mode Switching/Linear 5.0 V Regulator
