描述 Description

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.

特性 Features

? 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 theexcitation mode
? Supports compatible pins with STK672-740AN-E
