Descriptions

The RS31230 is a highly integrated dual efuse

specifically designed for the applications requiring

over-current protection, hot swap operation and inrush

current control.

With its bi-directional current support capability, the

device permits current flow in both directions: either

from ChxA to ChxB or vice vera.

Furthermore, the device is equipped with fixed

150mA bi-directional over-current protection that

comes with auto-retry feature.

Moreover, the device features two control pins that

allow for external control of both channels, enabling

opening and closing upon demand.

In addition, the device includes VDD over-voltage

protection and over-temperature protection.

The device is available in WLCSP 8 pins, 0.74x1.42

mm package.
