P2281

SINGLE SLEW RATE CONTROLLED LOAD SWITCH

Description

The AP2281 slew rate controlled load switch is a single P-channel

MOSFET power switch designed for high-side load-switching

applications. The MOSFET has a typical R

DS(ON)

of 80m at 5V,

allowing increased load current handling capacity with a low forward

voltage drop. The turn-on slew rate of the device is controlled

internally.

The AP2281 load switch is designed to operate from 1.5V to 6V,

making it ideal for 1.8V, 2.5V, 3.3V, and 5V systems. The typical

quiescent supply current is only 0.01µA.

Features

 Wide input voltage range: 1.5V – 6V

 Low R

DS(ON)

: 80mΩ typical @ 5V

 Turn-on slew rate controlled

 AP2281-1: 1ms turn-on rise time

 AP2281-3: 100µs turn-on rise time with internal discharge

 Very low turn-on quiescent current: << 1µA

 Fast load discharge option

 Temperature range -40°C to +85°C

 Lead-Free Finish; RoHS Compliant (Notes 1 & 2)

 Halogen and Antimony Free. “Green” Device (Note 3)

Applications

 Smart Phones

 PDA

 Cell Phones

 GPS Navigators

 PMP/MP4

 Notebook and Pocket PC
