Product Code: MIKROE-4271

The?Current Limit Click Board??is a compact add-on board that contains a low-voltage, P-channel MOSFET power switch intended for high-side load switching applications. This board features the?MAX890L, a low-resistance power switch with an adjustable, accurate current limit system, and thermal shutdown from?Maxim Integrated. Its internal current-limiting circuitry protects the input supply against overload, while thermal protection limits power dissipation. The maximum current limit is 1.2A and can be programmed through a digital potentiometer?MAX5401. The quiescent supply current has a low value of 10?A in the active state, while in its off state the supply current decreases to 0.1?A. This Click Board? is suitable for applications in some portable equipment, access bus slots, or with power supplies, protecting them in cases of a short circuit or other overload conditions.
