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)

簡介

STK531U394A-E屬于集成電路（IC）的全半橋驅(qū)動器。由制造生產(chǎn)的STK531U394A-E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。
