The MAX891LEUA+T from Analog Devices is a smart, low-voltage, P-channel MOSFET power switch suitable for high-side load-switching applications. It supports input voltages from 2.7V to 5.5V, making it ideal for both 3V and 5V systems.
Key features include internal current-limiting circuitry to protect the input supply against overload and thermal-overload protection to manage power dissipation. This specific model has a maximum current limit of 500mA, which can be programmed via an external resistor. The device exhibits a low quiescent supply current of 13µA when the switch is on and 0.1µA when off.
Designed for space-constrained applications, the MAX891LEUA+T is available in an ultra-small 8-pin µMAX package, measuring only 1.11mm high. It includes a FAULT indicator output and operates over an extended temperature range of -40°C to +85°C.
Applications for this power switch include PCMCIA slots, access bus slots, and portable equipment where efficient and protected power management is crucial.
