TEA3718SP集成電路（IC）的電機驅(qū)動器控制器規(guī)格書PDF中文資料

TEA3718SP屬于集成電路（IC）的電機驅(qū)動器控制器。由意法半導(dǎo)體集團制造生產(chǎn)的TEA3718SP電機驅(qū)動器，控制器產(chǎn)品屬于電機驅(qū)動器和控制器電源管理集成電路 (PMIC) 系列，可用于控制或操作從某電源施加到電機或相關(guān)機電執(zhí)行器的電源。所實現(xiàn)的具體功能和特性集根據(jù)預(yù)期負(fù)載和預(yù)期應(yīng)用的特性有很大差異，范圍從用于有刷電機的簡單開環(huán)速度控制到基于步進(jìn)電機的高級閉環(huán)運動控制。

Description

The circuits consist of an LS-TTL compatible logic input, a current sensor, a monostable and an output stage with built-in protection diodes. Two TEA3718 ICs and a few external components form a complete control and drive unit for LS-TTL or microprocessor-controlled stepper motor systems.

Features

■ Half-step and full-step mode

■ Bipolar drive of stepper motor for maximum motor performance

■ Built-in protection diodes

■ Wide range of current control 5 to 1500 mA

■ Wide voltage range 10 to 50 V

■ Designed for unstabilized motor supply voltage

■ Current levels can be selected insteps or varied continuously

■ Thermal overload protection

■ Alarm output or pre-alarm output

Applications

The TEA3718 is a bipolar monolithic integrated circuit intended to control and drive the current in one winding of a bipolar stepper motor.
