BTN9970LV集成電路（IC）的全半橋驅(qū)動器規(guī)格書PDF中文資料

BTN9970LV屬于集成電路（IC）的全半橋驅(qū)動器。由英飛凌科技股份公司制造生產(chǎn)的BTN9970LV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（如步進電機或無刷電機）所需的較大功率信號。

Description

The BTN9970LV is an integrated high current half-bridge for motor drive applications. It is part of the integrated

half-bridge NovalithIC?+ family containing one p-channel high-side MOSFET and one n-channel low-side

MOSFET with an integrated driver IC in one package. Due to the p-channel high-side switch the need for a

charge pump is eliminated thus minimizing EME. Interfacing to a microcontroller is made easy by the integrated driver IC which features logic level inputs, diagnosis with current sense, slew rate adjustment, dead time generation and protection against overtemperature, undervoltage, overcurrent and short circuit.

The BTN9970LV provides a cost optimized solution for protected high current PWM motor drives with very low board space consumption.
