Features

 Built-in overcurrent detection function, overheat detection function (output current OFF).
 FAULT signal (active low) is output when overcurrent or overheat is detected.
 Built-in power on reset function.
 The motor speed is controlled by the frequency of an external clock signal.
 2 phase or 1-2 phase excitation switching function.
 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 (0.089Ω: resistor tolerance 2%), motor current c.
