It is easily • 0.3A Maximum Switch Current integrated into system designs that have a 2.8V to • 0.64 Ω Typical Total On-Resistance 5.3V voltage rail. Besides the 0.45 Ω PFET switch, the LM34902 can be enabled or disabled by a logic • Load Detection signal. The IC monitors the presence of a • Enable/Disable downstream electronic device via a dedicated pin to • Switch On Indicator decide whether to turn on the PFET switch. A power good signal generated by the IC can be used by • Peak Current Limit system control to determine the status of the switch. • Thermal Shutdown The LM34902 also provides over-current and over- • 6-Bump Thin DSBGA Package temperature protection. The IC comes in a tiny 6- bump Thin DSBGA package. APPLICATIONS • Handsets, Tablets, Notebooks • Portable devices Typical Application Circuit 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
