SA9103E

sames FEATURES n SA9103E SINGLE PHASE BIDIRECTIONAL POWER/ENERGY METERING IC WITH SERIAL INTERFACE n Performs bidirectional active power/ energy measurement Meets the IEC 521/1036 Specification requirements for Class 1 AC Watt hour meters Protected against ESD Power consumption rating below 25mW Adaptable to different current sensor technologies Operates over a wide temperature range Serial interface having a RS232 protocol Precision voltage reference on-chip Tri-state output to allow parallel connection of devices. n n n n n n n DESCRIPTION The SAMES SA9103E Single Phase bidirectional Power/Energy metering integrated circuit has a serial interface with a RS232 protocol, ideal for use with a µController. The SA9103E performs the calculation for active power. The integrated value for active energy is accessable through the RS232-Interface as a 16 bit value. This innovative universal single phase power/energy metering integrated circuit is ideally suited for energy calculations in applications such as electricitydispensing systems (ED's), residential municipal metering and factory energy metering and control. The SA9103E integrated circuit is available in both 20 pin dual-in-line plastic (DIP-20), as well as 20 pin small outline (SOIC-20) package types.
