L6219D集成電路（IC）的電機驅(qū)動器控制器規(guī)格書PDF中文資料

L6219D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L6219D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電機的高級閉環(huán)運動控制。

DESCRIPTION

The L6219 is a bipolar monolithic integrated circuits intended to control and drive both winding of a bipolar stepper motor or bidirectionally control two DC motors.

The L6219 with a few external components form a complete control and drive circuit for LS-TTL or microprocessor controlled stepper motor system.

The power stage is a dual full bridge capable of sustaining 46V and including four diodes for current recirculation.

A cross conduction protection is provided to avoid simultaneous cross conduction during switching current direction.

An internal pulse-width-modulation (PWM) controls the output current to 750mA with peak start up current up to 1A.

Wide range of current control from 750mA (each bridge) is permitted by means of two logic inputs and an external voltage reference. A phase input to each bridge determines the load current direction.

A thermal protection circuitry disables the outputs if the chip temperature exceeds safe operating limits.
