L6204集成電路（IC）的全半橋驅(qū)動(dòng)器規(guī)格書(shū)PDF中文資料

L6204屬于集成電路（IC）的全半橋驅(qū)動(dòng)器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的L6204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(chēng)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(lèi)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)。

DESCRIPTION

The L6204 is a dual full bridge driver for motor

control applications realized in BCD technology

which combines isolated DMOS power transistors

with CMOS and Bipolar circuits on the same chip.

By using mixed technology it has been possible to

optimize the logic circuitry and the power stage to

achieve the best possible performance.

The logic inputs are TTL/CMOS compatible. Both

channels are controlled by a separate Enable.

Each bridge has a sense resistor to control the

currenrt level.

The L6204 is mounted in an 20-lead Powerdip and

SO 24+2+2 packages and the four center pins are

used to conduct heat to the PCB. At normal operating temperatures no external heatsink is required.
