STK672-732AN-E Datasheet PDF - ON Semiconductor

The STK672-732AN-E is a IPM for use a unipolar, 2-phase stepper motor driver IPM. It features the use of A, AB, B and BB 2-pahse input signals. It is with built-in current resistor. and motor current is set by the voltage on the Vref pin. In addition the STK672-732AN-E has various protective functions against over-current and over-heat. And it is pin-compatible with STK672-740AN-E.

●Features |   | Benefits

●---|---|---

● | |  | |  |

● Protective function against over-current and over-heat is built in (Output Current OFF)

●|   |

● Superior in safety drive

● Common-mode input protection circuit is built in

●|   |

● When A and AB (or B and BB) turn on at the same time, it prevents destruction

● Current detection resistors is built in

●|   |

● Easy to design and reduce the mounting area

● Built-in power on reset function

●|   |  

● Supports schmitt input for 2.5 V high level input

●|   |  

● Incorporating a current detection resistor (0.141 Ω : 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

●|   |  

● Supports compatible pins with STK672-740AN-E
