Pulse Input Bipolar Stepper Motor Driver

s GENERAL DESCRIPTION

s PACKAGE OUTLINE

NJU7384 is a bipolar drive stepping motor driver.

The control method used is a simple pulse train input control

(STEP & DIR) method of programming. Also, low power

consumption was realized as a result of the adoption of a highly

efficient CMOS.

As the control functions, the external input RESET and ENABLE

functions are used, and as the protective function, a thermal

shutdown (TSD) is incorporated.

The package uses the low thermal resistance SSOP32 which

can withstand a high output current.
