1 / 33 page  78M6613 Single-Phase AC Power Measurement IC DATA SHEET DS_6613_018 Rev 2 1 19-5348; Rev 2; 1/12 DESCRIPTION The Teridian™ 78M6613 is a highly integrated IC for simplified implementation of single-phase AC power measurement into power supplies, smart appliances, and other applications with embedded AC load monitoring and control. It is packaged in a small, 5mm x 5mm, 32-pin QFN package for optimal space savings. At the measurement interface, the device provides four analog inputs for interfacing to voltage and current sensors. Voltages from the sensors are fed to our Single Converter Technology® that uses a 22-bit delta-sigma ADC, independent 32-bit compute engine (CE), digital temperature compensation, and precision voltage references to provide better than 0.5% power measurement accuracy over a wide 2000:1 dynamic range. The integrated MPU core and 32 KB of flash memory provides a flexible means of configuration, post-processing, data formatting, and interfacing to any host processor through the UART interface and/or DIO pins. Complete application firmware is available and can be preloaded into the IC during manufacturing test. Alternatively, a complete array of ICE, development tools, and programming libraries are available to allow customization for each application. 80515 MPU TIMERS A0 A1 XIN XOUT VREF TX RX V3P3 GND DIO 4-8 DIO 14-17, 19 ICE SERIAL PORT OSC/PLL CONVERTER DIO, PULSE 32-bit COMPUTE ENGINE 32KB FLASH 2KB RAM VOLTAGE REF REGULATOR Earth Ground Isolated Supply TERIDIAN 78M6613 32 kHz LIVE NEUT ICE_E GND V3P3 TEMP SENSOR A2 A3 FEATURES • < 0.5% Wh Accuracy Over Wide 2000:1 Current Range and Over Temperature • Voltage Reference < 40ppm/°C • Four Sensor Inputs—V3P3A Referenced • 22-Bit Delta-Sigma ADC with Independent 32-Bit Compute Engine (CE) • 8-Bit MPU (80515), One Clock Cycle per Instruction with 2KB MPU XRAM • 32KB Flash with Security • Integrated In-Circuit Emulator (ICE) Interface for MPU Debug • 32kHz Time Base with Hardware Watchdog Timer • UART Interface and Up to 10 General- Purpose 5V Tolerant I/O Pins • Packaged in a RoHS-Compliant (6/6) Lead(Pb)-Free, 32-Pin QFN (5mm x 5mm) • Complete Application Firmware Provides: o True RMS Calculations for Current, Voltage, Line Frequency, Real Power, Reactive Power, Apparent Power, and Power Factor o Accumulated Watt-Hours, Kilowatt-Hours o Intelligent Switch Control at Zero Crossings o Digital Temperature Compensation o Phase Compensation (±15°) o Quick Calibration Routines o 46–64Hz Line Frequency Range with Same Calibration Teridian is a trademark and Single Converter Technology is a registered trademark of Maxim Integrated Products, Inc. |
