LV8044LP開發(fā)板套件編程器的評估演示板及套件規(guī)格書PDF中文資料

LV8044LP屬于開發(fā)板套件編程器的評估演示板及套件。由安森美半導(dǎo)體公司制造生產(chǎn)的LV8044LP評估和演示板及套件該系列產(chǎn)品提供了一種方便的方法，在經(jīng)過驗證的實施環(huán)境中評估某些重點器件的性能或特性。評估方法通常有完善的文檔說明，并且視乎具體情況由評估軟件提供支持。產(chǎn)品通常由印刷電路板組成，板上已裝有重點器件以及必要或有用的支持元器件，另外也可能包括其他組件，例如電纜或電源。對于數(shù)量特別多或類別獨特的器件類別(如 ADC、DAC 和開關(guān)模式電源)，評估平臺可組合為一個單獨的產(chǎn)品系列。

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.
