Description
The MP5493 is an energy backup and management unit that provides a very compact and efficient energy management solution for the power line carrier (PLC) in power meters. It consists of a buck DC/DC converter combined with a bidirectional DC/DC converter that supports a supercapacitor charger and boost topology. The MP5493 uses the bidirectional converter to achieve optimal energy transfer and to provide the most cost-effective energy storage solution.
The MP5493 achieves high power conversion efficiency across a wide load range by scaling down the switching frequency (fSW) under light-load conditions to reduce switching and gate driver losses. Thermal shutdown provides reliable, fault-tolerant operation.
The MP5493 is available in a cost-effective TSOT23-8 package.

SINGLE-PHASE SMART POWER METERSAPPLICATIONSingle-phase smart power meters area critical component of smart homes and the growing consumer focus on energy efficiency. Single-phase meters use a two-wire alternating circuit, consisting of a power (phase) wire and a neutral wire, with current flowing between these two wires. They are typically used for residential homes where lighting and heating are the main sources of energy consumption. Be...

APPLICATION
THREE-PHASE SMART POWER METERSAPPLICATIONThree-phase smart power meters area critical component of smart homes and the growing consumer focus on energy efficiency. Three-phase meters use a three-wire system (sometimes four), and can better accommodate higher loads compared to single-phase meters. Three-phase power meters are also more efficient and deliver power at a steadier, more consistent rate. They are typically used for commercial ...
