NJU7384
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.
