L6207Q集成電路（IC）的全半橋驅(qū)動器規(guī)格書PDF中文資料

L6207Q屬于集成電路（IC）的全半橋驅(qū)動器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的L6207Q全半橋驅(qū)動器器件屬于電橋驅(qū)動器電源管理集成電路 (PMIC) 系列，包含兩個或多個功率晶體管，以及在外部器件控制下將其用作開關(guān)所需的電路。這些晶體管通常在內(nèi)部配置為成對串聯(lián)連接（稱為半橋），因而任意指定晶體管對之間的結(jié)點都可以連接至兩個電源軌中的任一個。這類器件常用于將控制器件（如微控制器）提供的低電平信號轉(zhuǎn)換為操作執(zhí)行器（如步進(jìn)電機或無刷電機）所需的較大功率信號。

DESCRIPTION

The L6207 is a DMOS Dual Full Bridge designed for motor control applications, realized in MultiPower BCD technology, which combines isolated DMOS Power Transistors with CMOS and bipolar circuits on the same chip. The device also includes two independent constant off time PWM Current Controllers that performs the chopping regulation. Available in PowerDIP24 (20+2+2), PowerSO36 and SO24 (20+2+2) packages, the L6207 features a non-dissipative overcurrent protection on the high side Power MOSFETs and thermal shutdown.
