Product Summary

The lm34902itmx 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 lm34902itmx can be enabled or disabled by a logic signal. The IC monitors the presence of a downstream 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 status of the switch. The lm34902itmx also provides over-current and over-temperature protection. The IC comes in a tiny 6-bump Thin DSBGA package. The applications of the device are (1)Handsets, Tablets, Notebooks; (2)Portable devices.
