STK672-432B-E
Thick-Film Hybrid IC
2-phase Stepping Motor Driver
http://onsemi.com
Overview
The STK672-432B-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 motor terminal open detection function (output current OFF).
Built-in overcurrent detection function (output current OFF).
Built-in overheat detection function (output current OFF).
FAULT1 signal (active low) is output when any of motor terminal open, overcurrent, or overheat is detected.
The FAULT2 signal is used to output the result of activation of protection circuit detection at 3 levels.
Built-in power on reset function.
A micro-step sine wave-driven driver can be activated merely by inputting an external clock.
External pins can be used to select 2, 1-2 (including pseudo-micro), W1-2, 2 W1-2, or 4W1-2 excitation.
The switch timing of the 4-phase distributor can be switched by setting an external pin (MODE3) to detect either the
rise and fall, or rise only, of CLOCK input.
Phase is maintained even when the excitation mode is switched. Rotational direction switching function.
Supports schmitt input for 2.5V high level input.
Incorporating a current detection resistor (0.152Ω: resistor tolerance ±2%), motor current can be set using two
external resistors.
The ENABLE pin can be used to cut output current while maintaining the excitation mode.
With a wide current setting range, power consumption can be reduced during standby.
No motor sound is generated during hold mode due to external excitation current control.
