L6204屬于集成電路（IC）的全半橋驅動器。由意法半導體集團制造生產的L6204全半橋驅動器器件屬于電橋驅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所需的電路。這些晶體管通常在內部配置為成對串聯(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換為操作執(zhí)行器（如步進電機或無刷電機）所需的較大功率信號。

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.
