LM34902

300mA Current Limited Power Switch

General Description

Features

The LM34902 is a 0.3A PFET switch used to control the input

voltage of electronic devices. It is easily integrated into system

designs that have a 2.8V to 5.3V voltage rail. Besides the

0.45Ω PFET switch, the LM34902 can be enabled or disabled

by a logic signal. The IC monitors the presence of a down-

stream electronic device via a dedicated pin to decide whether

to turn on the PFET switch. A power good signal generated

by the IC can be used by system control to determine the sta-

tus of the switch. The LM34902 also provides over-current

and over-temperature protection. The IC comes in a tiny 6-

bump Thin Micro SMD package.
