Product Introduction

MAXQ3183 Low power consumption, multifunctional, multi-phase AFE with harmonic and tamper detection

description

MAXQ3183 is a dedicated power measurement front-end that collects and calculates multiphase voltage, current, power, energy, and many other metered and multiphase load power quality parameters. The calculation results can be retrieved through an external host via the Serial Peripheral Interface (SPI™) bus on the chip. The bus can also be used to monitor the operation of the external master configuration MAXQ3183 and to monitor the status of actions.

MAXQ3183 for voltage and current measurements, up to 7 external differential signal pairs can be measured using an integrated ADC. The eighth differential signal pair is used to measure the chip temperature. The internal amplifier automatically adjusts the current channel gain to compensate for the signal level of the low current channel.

Key features:

Compatible with 3-Phase/3-Wire, 3-Phase/4-Wire
Each phase of active power and energy, combined with 3 phases (kWh), positive and negative
Each phase and combined 3-phase reactive power and energy, positive and negative
Each phase and joint 3 phases are in power and energy
Neutral current measurement
The sum of the vectors of the 3-phase current and the neutral current
Line Frequency (Hz)
Power factor
Voltage phasor angle
Voltage and current phase sequence markers
Phase voltage loss detection
Voltage and current harmonic measurements
Phase current THDN
Basic and total electricity and energy
AC/DC mode measures current and voltage
Two pulse outputs: configurable for active power, reactive power, and apparent power

Ampere-hours at no voltage signal
On-chip digital temperature sensor
An accurate internal reference voltage of 2.048V (30ppm/°C typical) is also supported
Support software meter calibration
Nonlinear compensation of the sensor for multi-point calibration up to 3 points
Power failure detection
Bidirectional reset input/output
SPI-compatible serial interface (low-level IRQ) outputs interrupt requests
3.3V single supply, low power consumption (35MW typical)
Applications/Uses:
