Maxim - Adjustable current-limit switches feature internal current limiting to stop damage

Maxim Integrated MAX20333 Adjustable Current-Limit Switches feature internal current limiting to stop damage to host devices due to faulty load conditions. The switches provide a low 23mOhm (typ) on-resistance and operate from a +3.5V to +22V input voltage range.

The switches offer three working modes, a normal mode (NM), a high current mode (HCM), and a low power mode (LPM). In HCM, the current-limit threshold is multiplied by two, with an internal upper limit set at 5.5A. The voltage on SETI is proportional to the current flowing into IN but multiplied by a factor 0.5. In LPM, the current consumption of the part is dramatically reduced, and the on-resistance is 420mOhm (typ), while still providing an overcurrent protection. The switch is open when the current flowing through the switch exceeds 0.4A (typ).

The device can react in three different ways while in current limit: autoretry, latchoff, and continuous. The switches are available in a 15-bump (2.1mm x 1.52mm) WLP package and operate over the -40C to +85C extended temperature range.

Typical applications include USB port protection switch, battery disconnect switch, and general power supply switch.
