L6201PS集成電路（IC）的全半橋驅(qū)動(dòng)器規(guī)格書PDF中文資料

L6201PS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L6201PS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)。

DESCRIPTION

The I.C. is a full bridge driver for motor control applications realized in Multipower-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 DMOS output transistors can operate at supply voltages up to 42V and efficiently at high switching speeds. All the logic inputs are TTL, CMOS and μC compatible. Each channel (half-bridge) of the device is controlled by a separate logic input, while a common enable controls both channels.

The I.C. is mounted in three different packages.

■ SUPPLY VOLTAGE UP TO 48V

■ 5A MAX PEAK CURRENT (2A max. for L6201)

■ TOTAL RMS CURRENT UP TO

L6201: 1A; L6202: 1.5A; L6203/L6201PS: 4A

■ RDS (ON) 0.3 ? (typical value at 25 °C)

■ CROSS CONDUCTION PROTECTION

■ TTL COMPATIBLE DRIVE

■ OPERATING FREQUENCY UP TO 100 KHz

■ THERMAL SHUTDOWN

■ INTERNAL LOGIC SUPPLY

■ HIGH EFFICIENCY
