SA9103C

sames FEATURES n SA9103C SINGLE PHASE BIDIRECTIONAL POWER/ENERGY METERING IC WITH SERIAL INTERFACE n Performs bidirectional active and reactive power/energy, frequency and voltage measurement Meets the IEC 521/1036 Specification requirements for Class 1 AC Watt hour meters Protected against ESD Total 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 SA9103C bidirectional Single Phase Power/Energy metering integrated circuit has a serial interface with a RS232 protocol, ideal for use with a µ-Controller. The SA9103C performs the calculation for active and reactive power. The integrated values for active and reactive energy as well as the mains frequency and voltage information are accessable through the RS232-Interface as 16 bit values. This innovative universal single phase power/energy metering integrated circuit is ideally suited for energy calculations in applications such as electricity dispensing systems (ED's), residential municipal metering and factory energy metering and control. The SA9103C 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. 4259 PIN CONNECTIONS IIN IIP VREF CPON CPOP CPIN CPIP V DD TP9 OSC2 1 2 3 4 5 6 7 8 9 10 DR-0...
