Overview
The STK672-740A-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 (0.089Ω: resistor tolerance ±2%), motor current can be set using two
external resistors.
• Provides the output current cutoff ENABLE pin.
