Energy Measurement ICs
The MCP3905A, MCP3906A and MCP3909 are fully functional,
stand-alone energy measurement ICs that output average active
power. When these ICs are paired with a PIC microcontroller,
engineers have a complete, highly accurate solution for
energy measurement in residential and industrial power meter
applications.
These devices each integrate two 16-bit delta-sigma
analog-to-digital converters (ADCs), an internal voltage
reference, a programmable gain amplifier (PGA), and all digital
circuitry needed to calculate active power from voltage and
current channels. The MCP3905A features a PGA with a
maximum gain of 16 and a measurement error of 0.1% typical
over a dynamic range of 500:1. For energy meters requiring
higher accuracy, the MCP3906A has a PGA with a maximum
gain of 32 and a measurement error of 0.1% typical over a
dynamic range of 1000:1. For meters requiring additional
calculations, the MCP3909 can by used by accessing the ADC
data from the voltage and current channels and performing
calculations on a PIC MCU. These solutions meet or exceed the
requirements of the International Electrotechnical Commission
IEC62053 energy-metering specifications.
Microcontrollers with LCD Drivers
Most metering designs require user interfaces that are low
cost and easy to use. Microcontrollers with on-board liquid
crystal display (LCD) modules combine the control and interface
functions in a single device.
Microchip’s PIC18F85J90 and PIC16F917 series of 8-bit
microcontrollers provide high-performance and cost-effective
solutions for metering applications. Both families offer Flash
program memory, low power consumption and integrated LCD
control with a variety of features and package options.
8-/16-bit Microcontrollers and
16-bit Digital Signal Controllers
Engineers require a variety of controller options to select the
optimum price and performance for their applications. Microchip
offers hundreds of 8- and 16-bit microcontrollers and 16-bit
digital signal controllers for metering designs with numerous
choices of memory types and sizes, pin counts, peripherals and
much more.
Complete Technical Resources for
Metering Designs
Engineering resources are often limited, which makes access
to existing application reference designs and technical
documentation critical in reducing time to market.
