TDA21240数据手册集成电路（IC）的全半桥驱动器规格书PDF

描述 Description

DrMOS 4.0 x 4.0 x 1.0 mm³ offers best-in-class efficiency and very low power loss. Infineon can deliver these benefits by combining its latest generation 25V OptiMOS™ 5 MOSFET technologies with its proven MOSFET driver silicon. A significant reduction of switching losses enables superior efficiency at higher switching frequencies. Higher switching frequency operation, combined with an extremely small package, enables system designers to save board space and still deliver superior performance.

特性 Features

• Small 4.0 x 4.0 x 1.0mm³ PQFN package
• Fast switching technology for improved performance at high switching frequency (> 500kHz)
• Recommended input voltage 4.5V to 16V
• Undervoltage lockout › Shoot through protection
• 5V driver voltage optimized
• Compatible with standard 3.3V PWM

优势:
• Peak efficiency > 94%
• Integrated bootstrap diode (no need of external diode)
• Thermal warning
• Remote driver disable function

应用 Application

• Notebook, desktop and server VR buck converter
• Single-phase and multi-phase POL
• CPU/GPU regulation in notebook, desktop graphics cards

简介

TDA21240属于集成电路（IC）的全半桥驱动器。由制造生产的TDA21240全半桥驱动器器件属于电桥驱动器电源管理集成电路 (PMIC) 系列，包含两个或多个功率晶体管，以及在外部器件控制下将其用作开关所需的电路。这些晶体管通常在内部配置为成对串联连接（称为半桥），因而任意指定晶体管对之间的结点都可以连接至两个电源轨中的任一个。这类器件常用于将控制器件（如微控制器）提供的低电平信号转换为操作执行器（如步进电机或无刷电机）所需的较大功率信号。
