STK672-732A-E
Thick-Film Hybrid IC
2-phase Stepping Motor Driver
http://onsemi.com
Overview
The STK672-732A-E is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control.
Applications
Office photocopiers, printers, etc.
Features
Built-in overcurrent detection function (output current OFF).
Built-in overheat detection function (output current OFF).
If either overcurrent or overheat detection function is activated, the FAULT signal (active low) is output.
Built-in power on reset function.
Phase signal input driver activated with an active Low and incorporates a simultaneous ON prevention function.
Supports schmitt input for 2.5V high level input.
Incorporating a current detection resistor (0.141Ω: resistor tolerance ±2%), motor current can be set using two
external resistors.
Provides the output current cutoff ENABLE pin.
Miniature package (provides pin compatibility with STK672-730A-E)
