L2293Q数据手册集成电路（IC）的全半桥驱动器规格书PDF

描述 Description

The device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoides, DC and stepping motors) and switching power transistors.

To simplify use as two bridges each pair of channels is equipped with an enable input. A separate supply input is provided for the logic, allowing operation at a lower voltage and internal clamp diodes are included.

This device is suitable for use in switching applications at frequencies up to 5 kHz.

The L2293Q is assembled in a VFQFPN-32L 5x5 package which has exposed pad available for heatsinking.

特性 Features

• Internal clamp diodes
• 600 mA output current capability per channel
• Enable facility
• 1.2 A peak output current (non repetitive) per channel
• Logical \\\"0\\\" input voltage up to 1.5 V (high noise immunity)
• Overtemperature protection

简介

L2293Q属于集成电路（IC）的全半桥驱动器。由制造生产的L2293Q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。
