SGM4541中文资料I²C Bus Over-Voltage Protector数据手册SGMICRO规格书

描述 Description

The SGM4541 is a low IQ I2C bus over-voltage protector. When the voltage at SCLA or SDAA pin exceeds VCC + 0.69V, the switches (S1 and S2) between SCLA and SCLB, or SDAA and SDAB will be turned off. When the voltage at SCLA or SDAA pin is less than VCC + 0.69V, the switches (S1 and S2) will be turned on automatically. SCLA and SDAA I/O signals can endure continuous 22V high voltage without any damage. These pins can endure continuous 24V high voltage without any damage for 3 hours.
The SGM4541 is available in a Green UTDFN-1.45×1-6AL package.
