PRELIMINARY DATASHEET - 12/4/2002

(Subject to change without notice)

DMOS DUAL FULL-BRIDGE

PWM MOTOR DRIVER

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.

ABSOLUTE MAXIMUM RATINGS

at T = +25°C

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 1µA 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.

Load Supply Voltage, VBB ..........................20 V

Output Current, I_OUT............................ ±500 mA*

Logic Supply Voltage, V_DD..........................7.0 V

Logic Input Voltage Range,

V_IN......................-0.3 V to V_DD+ 0.3 V

(t_W<30ns)..................-1.0V to V_DD+1V

Sense Voltage, V_SENSE..................................0.5 V

Reference Voltage, V_REF.................................3 V

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.

Package Power Dissipation (T = +25°C), P_D

A3965SLB........................... 50°C/W**

Internal circuit protection includes thermal shutdown with

hysteresis, undervoltage monitoring of V_DDand charge pump, and crossover

current protection. Special power up sequencing is not required.

Operating Temperature Range,

T_A................................ -20°C to +85°C

Junction Temperature, T_J......................... +150°C

Storage Temperature Range,

The A3965 is supplied in a 24-lead plastic SOIC with a copper

batwing tab (suffix ‘LB’).

T_S............................... -55°C to +150°C

* Output current rating may be limited by duty cycle,

ambient temperature, and heat sinking. Under any set of

conditions, do not exceed the specified current rating or a

junction temperature of 150°C.

*Measured with 062" thick FR4, two sided PCB with 1 sq

inch copper area.

FEATURES

±500 mA, 20 V Output Rating
