Overview
sames FEATURES n SA9105A THREE PHASE UNIDIRECTIONAL POWER/ENERGY METERING IC WITH PULSE OUTPUT n n Performs unidirectional one, two or three phase power and energy measurement Meets the IEC 521/1036 Specification requirements for Class 1 AC Watt hour meters Operates over a wide temperature Range Uses current transformers for current sensing Excellent long term stability Easily adaptable to different signal levels Precision voltage reference on-chip Three pulse rate outputs available Protected against ESD n n n n n n PIN CONNECTIONS DESCRIPTION The SAMES SA9105A Three Phase unidirectional Power/Energy metering 40 CIN1 1 CIP2 2 integrated circuit generates a pulse rate 39 38 CIN2 3 output, the frequency of which is proportional CIP3 4 37 to the power consumption.
The SA9105A 36 CIN3 5 performs the calculations of active power.
6 35 IIN1 The method of calculation takes the power IIP1 7 34 factor into account.
8 33 IIN2 Energy consumption is determined by the 32 9 IIP2 31 IIN3 10 power measurement being integrated over IIP3 11 30 time.
29 COPP 12 The output of this innovative universal three 28 CONP 13 phase power/energy metering integrated CIPP 14 27 circuit, is ideally suited for applications such 26 CINP 15 as residential and industrial energy metering 25 V SS 16 and control.
TP17 17 24 TP18 18 The SA9105A integrated circuit is available 23 OSC1 19 22 in 40 pin dual-in-line plastic (DIP-40), as 21 OSC2 20 well as in 44 pin plastic leaded chip carrier DR-00838 (PLCC-44) packages types.
