ILA19002

SINGLE PHASE BIDIRECTIONAL POWER/ENERGY

METERING IC WITH INSTANTANEOUS PULSE OUTPUT

FEATURES

• Performs bidirectional power

• Total power consumption rating

below 25 mW

and energy measurement

• Meets the IEC 521/1036

Specification requirements for

Class 1 AC Watt hour meters

• Protected against ESD

• Adaptable to different types of

current sensors

• Operates over a wide temperature

range

• Precision voltage reference on-chip

FUNCTIONAL DESCRIPTION:

The ILA19002 Single Phase Bidirectional Power/Energy metering integrated circuit generates

a pulse rate output, the frequency of which is proportional to the power consumption. The

ILA19002 performs the calculations of active power.

The method of calculation takes the power factor into account.

Energy consumption is determined by the power measurement being integrated over time.

This universal single phase bidirectional power/energy metering integrated circuit is ideally

suited for energy calculation in applications such as residential municipal metering and factory

energy metering and control.

The ILA19002 Single Phase Bidirectional Power/Energy metering integrated circuit is a

CMOS mixed signal Analog/Digital integrated circuit, which performs power/energy

calculations over a range of 1000:1, to an overall accuracy of better than Class 1.

The integrated circuit includes all the required functions for 1-phase power and energy

measurement such as two oversampling A/D converters for the voltage and current sense

inputs, power calculation and energy integration. Internal offsets are eliminated through the

use of cancellation procedures.

The ILA19002 Single Phase Bidirectional Power/Energy metering integrated circuit generates

pulses, the frequency of which is proportional to the power consumption. The pulse rate

follows the instantaneous power consumption measured. Direction information is also

provided. A voltage zero crossover signal, relevant to the positive going half cycle, is available

on pin FMO. This signal can be used to synchronise circuit breaker switching.

IC is available in both 14 and 20 pin dual-in-plastic (DIP-14/DIP-20), as well as 20 pin small

outline (SOIC-20) package types.
