MAX891LEUA Description

Short technical summary and product information.

The MAX891LEUA is a smart, low-voltage, P-channel MOSFET power switch designed for high-side load-switching applications. It operates with input voltages from 2.7V to 5.5V, making it suitable 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 limit power dissipation. The MAX891L variant has a maximum current limit of 500mA, with the limit programmable via an external resistor. It boasts a low quiescent supply current of 13µA when the switch is on and 0.1µA when off.

 

This device is available in an ultra-small 8-pin µMAX package, measuring only 1.11mm high. Its typical on-resistance is 120mΩ. The switch includes a FAULT indicator output and supports an On/Off interface.

 

Applications for the MAX891LEUA include PCMCIA slots, Access Bus slots, and portable equipment, where efficient and protected power switching is required.
