L6235PD013TR集成電路（IC）的電機驅(qū)動器控制器規(guī)格書PDF中文資料

L6235PD013TR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L6235PD013TR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 L6235 device is a DMOS fully integrated 3-phase motor driver with overcurrent protection. Realized in BCD technology, the device combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. The device includes all the circuitry needed to drive a 3-phase BLDC motor including: a 3-phase DMOS bridge, a constant off time PWM current controller and the decoding logic for single ended hall sensors that generates the required sequence for the power stage.
