ETA6123 Datasheet | ETA

DESCRIPTION ETA6123 is an Over-Voltage-Protection (OVP) IC with an ultra-low 40mΩ RDSON high current high voltage MOSEFT and an integrated TVS device to improve surge protection. It can wok with a DC input voltage as high as 24.5V DC, above which, the integrated TVS will start to function by clamping any higher voltage to around 30V (given 80V 8/20us surge test condition). When input voltage of ETA6123 exceed the OVP threshold, it responses quickly and shuts off the MOSFET. The OVP threshold is fixed internally. There is also an over-current-protection feature for the switch. When overload condition occurs, it goes into a hiccup mode to protect the IC from over-heating. It also has an over-temperature protection feature that turns off the MOSFET. ETA6123 is available in FCQFN1.2x1.2-9L and SOT23-6 package.
