NJU7384

www.DataSheet4U.com 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 NJU7384V can withstand a high output current. s FEATURES Operating Voltage 3.0 to 5.5V（Logic : VDD） 4.0 to 8.0V（H bridge : VMM） Maximum Output Current 700mA/ch Pulse Input (STEP＆DIR) Control Half / Full Step Change Function Thermal Shutdown Circuit Thermal Shutdown Alarm Output RESET Function ENABLE Function CMOS Technology Package Outline SSOP32 s BLOCK DIAGLAM VDD VMM1 GATE DRIVE STEP OUTA1 OUTA2 DIR CONTROL LOGIC TRANSLATOR PGNG1 VMM2 GATE DRIVE HSM RESET OUTB1 OUTB2 ENABLE PGND2 GND TSD TSD ALARM Ver.2007-08-20 -1- NJU7384 s PIN FUNCTION www.DataSheet4U.com 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 1.
