BD63720AEFV-E2集成電路（IC）的電機驅(qū)動器控制器規(guī)格書PDF中文資料

BD63720AEFV-E2屬于集成電路（IC）的電機驅(qū)動器控制器。由羅姆半導體集團制造生產(chǎn)的BD63720AEFV-E2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)預期負載和預期應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。

General Description

BD63720AEFV is a bipolar low-consumption driver that

driven by PWM current. Rated power supply voltage of

the device is 36 V, and rated output current is 2.0 A.

CLK-IN driving mode is adopted for input interface, and

excitation mode is corresponding to FULL STEP mode,

HALF STEP mode (2 types) and QUARTER STEP

mode via a built-in DAC. In terms of current decay, the

FAST DECAY/SLOW DECAY ratio may be set without

any limitation, and all available modes may be

controlled in the most appropriate way. In addition, the

power supply may be driven by one single system,

which simplifies the design.
