By replacing current transformers with shunts, the DS8102 and MAXQ3108 chipset reduces system cost and board space for a polyphase electricity meter.

The DS8102 contains two delta-sigma modulators with programmable gain to 32x. Outputs from the two modulators are encoded into a single bit stream to minimize the cost of data coupling.

The MAXQ3108 is a dual-core RISC controller with three Manchester decoding blocks and three cubic-sinc filters for the companion DS8102 devices. Maxim provides an implementation of a polyphase, multifunction energy-metering DSP, and a complete reference design.

This chipset is ideally suited for polyphase electricity meters.

Driving transistor-size to sub-microns level, the MLX90248 New Generation brings noticeable key improvements for growing and more demanding portable and handheld devices.

The latest cutting edge technology embedded in the device helps to make applications making use of it go green.

Based on the Hall-Effect principle, the MLX90248 provides a magnetic contact-less and solid-state switching for application where special power management schemes such as standby mode are a must in order to save battery power or reduce overall power-consumption.

By the use of a very high sensitivity Hall sensor, a very small and cheap magnet is enough to trigger the MLX90248, hence it can easily replace reed switch. The major benefit of using a Hall sensor is to provide “electronic” commutation, which is bounce-free, more reliable and with increased lifetime compared to usual mechanical contacts.
