The SGM4541A is a low IQ I2C bus over-voltage protector which supports with IEC61000-4-2 Standard ±12kV (Air / Contact) ESD protection on SCLA, SCLB, SDAA and SDAB pins. Transient voltage suppression (TVS) protection diodes are integrated on each SCLA, SCLB, SDAA and SDAB pins. When the voltage at SCLA or SDAA pin exceeds VCC + 0.68V, the switches (S1 and S2) between SCLA and SCLB, SDAB and SDAA will be turned off. When the voltage at SCLA or SDAA pin is less than VCC + 0.68V, the switches (S1 and S2) will be turned on automatically. All these I/O signals (SCLA, SCLB, SDAA and SDAB) can endure continuous 22V high voltage without any damage. These pins can endure continuous 24V high voltage without any damage during 3 hours.
The SGM4541A is available in Green UTDFN-1.5×1.5-6AL package.
