Mikroe Current Limit Click

Mikroe Current Limit Click contains a low-voltage, P-channel MOSFET power switch for high-side load switching applications. The Mikroe Current Limit Click board features an Analog Devices / Maxim Integrated MAX890L low-resistance power switch with an adjustable, accurate current limit system and thermal shutdown. The switch's internal current-limiting circuitry protects the input supply against overload. The device's thermal protection limits power dissipation. The maximum current limit is 1.2A, programmed through a MAX5401 digital potentiometer. The quiescent supply current has a low value of 10μA in the active state, while in its off state, the supply current decreases to 0.1μA.
