BD6221F-E2集成電路（IC）的全半橋驅(qū)動(dòng)器規(guī)格書(shū)PDF中文資料

BD6221F-E2屬于集成電路（IC）的全半橋驅(qū)動(dòng)器。由羅姆半導(dǎo)體集團(tuán)制造生產(chǎn)的BD6221F-E2全半橋驅(qū)動(dòng)器器件屬于電橋驅(qū)動(dòng)器電源管理集成電路 (PMIC) 系列，包含兩個(gè)或多個(gè)功率晶體管，以及在外部器件控制下將其用作開(kāi)關(guān)所需的電路。這些晶體管通常在內(nèi)部配置為成對(duì)串聯(lián)連接（稱為半橋），因而任意指定晶體管對(duì)之間的結(jié)點(diǎn)都可以連接至兩個(gè)電源軌中的任一個(gè)。這類器件常用于將控制器件（如微控制器）提供的低電平信號(hào)轉(zhuǎn)換為操作執(zhí)行器（如步進(jìn)電機(jī)或無(wú)刷電機(jī)）所需的較大功率信號(hào)。

Overview

These H-bridge drivers are full bridge drivers for brush motor applications. Each IC can operate at a wide range of power supply voltages (from 3V to 36V), supporting output currents of up to 2A. MOS transistors in the output stage allow for PWM signal control, while the integrated VREF voltage control function of previous models offers direct replacement of deprecated motor driver ICs. These highly efficient H-bridge driver ICs facilitate low-power consumption design.

特性 Features

1) Built-in, selectable one channel or two channels configuration

2) Low standby current

3) Supports PWM control signal input (20kHz to 100kHz)

4) VREF voltage setting pin enables PWM duty control

5) Cross-conduction prevention circuit

6) Four protection circuits provided: OCP, OVP, TSD and UVLO

Applications

VCR; CD/DVD players; audio-visual equipment;

optical disc drives; PC peripherals;

car audios; car navigation systems; OA equipments
