LB11660RV-W-AH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LB11660RV-W-AH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 LB11660RV is a single-phase bipolar half pre-driver that can achieve high-efficient direct PWM drive with ease. It is ideal for driving small-sized cooling fans used in servers. The LB11660RV is provided with the RD (lock detection) output pin and the LB11660FV the FG (rotational speed detection) output pin, respectively.

Features

? Single-phase full-wave drive (15V-1.5A output transistor built in) upper output Tr incorporated half pre-driver.

? Variable speed control by an external signal.

->Separately-excited upper TR direct PWM control method, enabling silent, low-vibration variable speed control.

? Lowest speed setting possible.

? Current limiter circuit (the circuit actuated at IO = 1A when Rf = 0.5?, Rf determines the limiter value.)

? Kickback absorption circuit built in.

? Soft switching circuit achieves low power consumption, low loss, and low noise driving at a time of phase change.

? HB built in.

? Lock protection and automatic reset functions incorporated (including a circuit that changes the ON/OFF ratio according to the power supply voltage).

? RD (lock detection) output.

? Thermal protection circuit incorporated (design guaranteed).
