MCP3909 3-Phase Energy Meter Reference Design

(MCP3909RD-3PH1)

This reference design is a fully functional 3-phase

energy meter including PC software used for automated

calibration. The reference design consists of two boards:

the main metering board with the MCP3909 devices and

PIC18F2520 that performs the power calculations, and the

USB interface module which uses the PIC18F4550. The

meter design contains serially accessible registers and is

intended to be flexible and upgraded with a variety of PIC

microcontrollers using the included firmware.

easily jumpered into systems for development purposes.

This board also interfaces with the PICDEM HPC Explorer,

PICDEM FS USB and PICDEM LCD demo boards.

Operational Amplifiers

MCP6V01 Thermocouple Auto-Zeroed Reference

Design Board (MCP6V01RD-TCPL)

The MCP6V01 design board

demonstrates how to use a difference

amplifier system to measure

Electromotive Force (EMF) voltage at the

cold junction of thermocouple in order

to accurately measure temperature of the thermocouple

bead. This can be done by using the MCP6V01 auto-

and high Common Mode Rejection Ratio (CMRR).

MCP651 Input Offset Evaluation Board (MCP651EV-VOS)

This evaluation board provides a simple means to measure the

boards op amp input offset voltage under a variety of operating

changes due to: power supply voltage (PSRR), common mode

voltage (CMRR), output voltage (AOL), input offset voltage drift

MCP6V01 Input Offset Demo Board (MCP6V01DM-VOS)

This demo board provides a simple means to measure the

MCP6V01/2/3 op amps input offset voltage under a variety

voltage value found in the data sheet plus changes due to

power supply voltage, common mode voltage, output voltage

and temperature.

Power Management

MCP1640 Synchronous Boost Converter Evaluation

Board (MCP1640EV-SBC)

This board uses the MCP1640 in a high-efficiency

(up to 96%), fixed frequency (500 MHz), step-up

DC-DC converter. It demonstrates a minimum

number of external component power supply

solutions for applications powered by alkaline,

NiCd/NiMH or one-cell Li-Ion or Li-Polymer batteries.

MCP1630 Boost Mode LED Driver Demo Board

(MCP1630DM-LED2)

This demo board is a step-up, switch-mode, DC-DC converter

used for power LED applications. The demo board provides

a 350 mA or 700 mA constant current source with a jumper

selection. The input operating voltage range is 9-16V DC and

the board can supply up to 30W to a string of power LEDs.

MCP1631HV Multi-Chemistry Battery Charger

Reference Design (MCP1631RD-MCC2)

This reference design board is used to charge one to five NiMH or

NiCd batteries, charge one or two cell Li-Ion batteries, or drive one

or two 1W LEDs. The board uses the MCP1631HV high speed

analog PWM and PIC16F833 to generate the charge algorithm for

NiMH, NiCd or Li-Ion batteries.

Thermal Management

TC1047A Temp-to-Voltage Converter PICtail

Demo Board (TC1047ADM-PICTL)

This board demonstrates how to interface the

TC1047A device to a MCU. Connects directly to

the PICkit 3 Starter Kit, providing a platform for

code development and evaluation. Demonstrates

a good example of how to integrate an analog

temperature sensor into a system.

MCP9700 Thermistor Demo Board (MCP9700DM-TH1)

This demo board contains analog circuitry to measure

temperature. The board uses BC Components’ 232264055103

NTC thermistor to convert temperature to resistance. The

thermistor is placed in a voltage divider which converts

resistance to voltage. This voltage is filtered and placed at the

MCP6S22 Programmable Gain Amplifier’s (PGA) CH0 input. The

PGA gains and buffers the thermistor.
