LB11850VA屬于集成電路(IC)的電機(jī)驅(qū)動(dòng)器控制器。由安森美半導(dǎo)體公司制造生產(chǎn)的LB11850VA電機(jī)驅(qū)動(dòng)器,控制器產(chǎn)品屬于電機(jī)驅(qū)動(dòng)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(jiǎn)單開(kāi)環(huán)速度控制到基于步進(jìn)電機(jī)的高級(jí)閉環(huán)運(yùn)動(dòng)控制。
Overview
The LB11850VA is a single-phase bipolar fan motor driver with speed control function that works with a speed feedback signal. A highly efficient, quiet and low power consumption motor driver circuit, with a high speed accuracy and large variable speed can be implemented by adding a small number of external components.
This pre-driver is optimal for driving large scale fan motors (with large air volume and large current) such as those used in servers and consumer products.
Functions and Features
? Pre-driver for Single-phase Full-wave Drive
? PMOS-NMOS is Used as an External Power TR, Enabling High-efficiency and Low-power-consumption Drive by Means of the Low-saturation Output and Single-phase Full-wave Drive
? On-chip Speed Control Circuit
? The Speed Control (Closed Loop Control) Using a Speed Feedback Signal Makes it Possible to Achieve Higher Speed Accuracy and Lower Speed Fluctuations when Supply Voltage Fluctuates or Load Fluctuates, Compared with an Open-loop Control System. Separately Excited Upper Direct PWM Control Method is Used as the Variable-speed Control System
? External PWM Input or Analog Voltage Input Enabling Variable Speed Control
? The Speed Control Input Signal is Compatible with PWM Duty Ratio or Analog Voltages
? On-chip Soft Start Circuit
? Lowest Speed Setting Pin
? The Lowest Speed can be Set with the External Resistor
? Current Limiter Circuit Incorporated
? Chopper Type Current Limit at Start or Lock
? Reactive Current Cut Circuit Incorporated
? Reactive Current before Phase Change is Cut to Enable Silent and Low-consumption Drive
? Constraint Protection and Automatic Reset Functions Incorporated
? FG (Speed Detection), RD (Lock Detection) Output
? Constant-voltage Output Pin for Hall Bias
