STK531U394A-E数据手册集成电路（IC）的全半桥驱动器规格书PDF

描述 Description

This “Inverter IPM” is highly integrated device containing all High Voltage (HV) control from HV-DC to 3-phase outputs in a single SIP module (Single-In line Package). Output stage uses IGBT / FRD technology and implements Under Voltage Protection (UVP) and Over Current Protection (OCP) with a Fault Detection output flag. Internal Boost diodes are provided for high side gate boost drive.

特性 Features

Protective circuits including over current (bus line) and pre-drive low voltage protection are built in.
Fast speed protection is possible (Self protection)
Direct input of CMOS level control signals without insulating circuits is possible. (Active HIGH)
No need photo-coupler design
A single power supply drive is enabled through the use of bootstrap circuits for upper power supplies. (externally set)
No need bootstrap diode and resistor at externally
Built-in simultaneous upper/lower ON prevention circuit to prevent arm shorting through simultaneous ON input for the upper and lower side transistors.(Dead time is required for preventing shorting due to switching delay.)
All IGBT Gate shutdown at abnormal for safety
The level of the overcurrent protection current can be changed with the external resistor “RSD” between the “ISD” and “VSS” terminals.
Can be customized by each application
Monitoring substrate temperature is possible through the use of an internal thermistor.
High precision monitor is possible
Certification : UL Recognized (File number : E339285)

简介

STK531U394A-E属于集成电路（IC）的全半桥驱动器。由制造生产的STK531U394A-E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。
