The MAX890LESA+T 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. The device includes internal current-limiting circuitry to protect the input supply against overload and thermal-overload protection to limit power dissipation and junction temperatures.
Key features include a programmable current limit, which can be set with an external resistor. The switch offers a low quiescent supply current of 10µA typically at VIN = +3.3V, decreasing to 0.1µA typically when the switch is off. It also provides a FAULT indicator output. The MAX890LESA+T has an on-resistance of 0.09Ω typically and is available in an 8-pin SO package.
This power switch is ideal for applications such as PCMCIA slots, access bus slots, and portable equipment. Its robust protection features and low power consumption make it a versatile component for power management solutions.
