LV8044LP-TLM-H集成電路（IC）的電機(jī)驅(qū)動器控制器規(guī)格書PDF中文資料

LV8044LP-TLM-H屬于集成電路（IC）的電機(jī)驅(qū)動器控制器。由安森美半導(dǎo)體公司制造生產(chǎn)的LV8044LP-TLM-H電機(jī)驅(qū)動器，控制器產(chǎn)品屬于電機(jī)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(jī)或相關(guān)機(jī)電執(zhí)行器的電源。所實(shí)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(jī)的簡單開環(huán)速度控制到基于步進(jìn)電機(jī)的高級閉環(huán)運(yùn)動控制。

Overview

The LV8044LP is a 6-channel motor driver IC for digital still camera.

Functions

? Two microstep drive H-bridge driver channels.

? Two microstep drive/PWM saturated drive switchable H-bridge driver channels.

? Two constant-current drive H-bridge driver channels.

? Drive mode switchable between 2-phase, 1-2 phase full torque, 1-2 phase, and 4W1-2 phase (channels 1, 2, 3, and 4).

? Microstep drive step advance controlled by a single step signal input (channels 1, 2, 3, and 4).

? Ability to set the hold current to one of four levels (channels 1, 2, 3, and 4).

? Ability to set the constant-current reference voltage to one of 16 levels from the serial data (channels 5 and 6).

? Eight-bit 3-wire serial control.

? Three on-chip photosensor driver circuits.
