Designed for Pulse Width Modulated (PWM) current control of low
voltage stepper motors, the A3965S is capable of output currents to
±
500 mA
and operating voltages to 20 V.
The A3965 is particularly attractive for low power or battery
operated motors where minimal power consumption is desired. A SLEEP
mode disables all circuitry and typically draws less than 1
μ
A supply current
from motor and logic supply. During operation the fixed frequency ON
pulses of each H-bridge are 180 degrees out of phase to minimize the peak
demand required of the motor supply allowing savings in size and cost of
external power supply components.
PHASE and ENABLE input terminals are provided for use in
controlling the speed and direction of a stepper motor with externally applied
PWM control signals.
Internal circuit protection includes thermal shutdown with
hysteresis, undervoltage monitoring of V
DD
and charge pump, and crossover
current protection. Special power up sequencing is not required.
The A3965 is supplied in a 24-lead plastic SOIC with a copper
batwing tab (suffix ‘LB’).
