NTE1885 Product details

Description

of Operation: Constant Current Chopper Drive a) When the phase drive input is activated, the motor winding current increases. OFF to maintain a constant current. current chopper drive by PWM offering a higher efficiency (30% under a certain condition) than a constant voltage drive, but causing relatively large noise due to the switc

Features

D Low heat generation due to constant current chopper system. D Functions of pause action and power down. D Able to be used in any stepping motor of hybrid typ, P. M. type, V. R. type. D Inverter buffer provides direct drive, for 4 phase dual excitation. D Built in sensing power resistors for load current. D Protection elements for fly.
back voltage are included. Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Supply Voltage, VCC (Quiescent).
