MAX891LEUA+T Description

Short technical summary and product information.

The MAX891LEUA+T is a smart, low-voltage, P-channel MOSFET power switch designed for high-side load-switching applications. It is suitable for both 3V and 5V systems, operating with an input voltage range of 2.7V to 5.5V. Internal circuitry provides protection against overload conditions through current limiting and thermal shutdown.

 

Key electrical features include a programmable current limit, which can be set using an external resistor. The device offers a low quiescent supply current of 13µA when the switch is on and a significantly lower 0.1µA when off. The MAX891L variant has an on-resistance of 0.12Ω and a maximum current limit of 500mA, while the MAX892L variant has an on-resistance of 0.25Ω and a maximum current limit of 250mA.

 

This power switch is available in an ultra-small 8-pin µMAX package, measuring only 1.11mm high. It also includes a FAULT indicator output. Applications include PCMCIA slots, access bus slots, and portable equipment. The operating temperature range for the MAX891LEUA+T is -40°C to +85°C.
