NEW PRODUCT AP22800 5V SINGLE CHANNEL PROGRAMMABLE LOAD SWITCH Description The AP22800 is an integrated N-channel load switch, which features an adjustable ramp-up and discharge rate that are settable via an external capacitor and a resistor, respectively. In addition, it incorporates a ‘power good’ output to flag when the switch is enhanced. The N-channel MOSFET has a typical RDS(ON) of 16mΩ, enabling current handling capability of up to 4A. The AP22800 is designed to operate from 1.5V to 5.5.

NEW PRODUCT AP22800 5V SINGLE CHANNEL PROGRAMMABLE LOAD SWITCH Description The AP22800 is an integrated N-channel load switch, which features an adjustable ramp-up and discharge rate that are settable via an external capacitor and a resistor, respectively. In addition, it incorporates a ‘power good’ output to flag when the switch is enhanced. The N-channel MOSFET has a typical RDS(ON) of 16mΩ, enabling current handling capability of up to 4A. The AP22800 is designed to operate from 1.5V to 5.5V making it ideal for 1.8V, 2.5V, 3.3V, 5V voltage rails. The low quiescent supply current specification of 21µA makes it ideal for use in battery powered distribution systems where power consumption is a concern. The AP22800 is available in a standard Green U-DFN2116-8 package with an exposed PAD for improved thermal performance and is RoHS compliant. Features  1.5V to 5.5V Input Range  Low Typical RDS(ON) of 16mΩ  Very Low Quiescent Current of 21µA  Adjustable Start-Up and Discharge Rate  Small Form Factor Package U-DFN2116-8 – Footprint of just 3.36mm2  Thermally Efficient Low Profile  Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)  Halogen and Antimony Free. “Green” Device (Note 3) Pin Assignments Top View Bottom View VIN 1 VIN 2 EN 3 SS 4 GND 8 VOUT 8 7 VOUT 7 6 DIS 6 5 PG 5 U-DFN2116-8 GND 1 VIN 2 VIN 3 EN 4 SS Applications  Integrated Load Switches in Ultrabook PCs  Power Up/Down Sequencing in Ultrabook PCs  Tablets  SSD (Solid State Drives)  Consumer Electronics  Telecom Systems  Set-top Boxes  E-Readers Notes: 1.
