APPLICATIONS
● Office photocopiers, printers, etc.FEATURES
● The motor speed can be controlled by the frequency of an external clock signal.● 2-phase excitation or 1-2 phase excitation is selected according to switching the state of the MODE pin (low or high).
● The phase is maintained even if the excitation mode is switched in the middle of operation.
● The direction of rotation can be changed by applying a high or low signal to the CWB pin used to select the direction of rotation.
● Supports schmitt input for 2.5V high level input.
● Incorporating a current detection resistor (0.11Ω: resistor tolerance ±2%), motor current can be set using two external resistors.
● Equipped with an ENABLE pin that, during clock input, allows motor output to be cut-off and resumed later while maintaining the same excitation timing. Semiconductor Components Industries, LLC, 2013 June, 2013 62911HKPC 018-08-0038/71608HKIM No. A0754-1/22 STK672-540 Specifications
