STK672-732AN-E数据手册集成电路（IC）的电机驱动器控制器规格书PDF

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

应用 Application

• Computing & Peripherals
• Industrial
• Multi-Function Printer
• Document Scanner
• Auto Trading Machine
• Vending Machine
