Stmicroelectronics (STPM33TR) Single Phase Energy Metering

Single Phase Energy Metering, 2.95 V to 3.65 V in, QFN-32 Product Overview The STPM33TR is a high accuracy Analog Front End (AFE) for DC and AC energy measurement, offering high accuracy down to extremely low current typical of home appliances in stand-by. A full set of on-board features provides high system integration and enable on-chip power quality monitoring. The device has up to 4 independent 24 bits 2nd order ∑Δ ADC with PGA. The device has integrated DSP for "turn-key" energy parameters calculations. Built-in twin independently temperature compensated voltage references and double LED output programmable for active and reactive energy pulses generation. Applicable to class 0.2m <0.1% Active power accuracy over a dynamic range of 5000:1 4kHz Bandwidth Very fast single point calibration AC and DC measurement Multiple sensors support - Shunt, current transformer, Rogowsky coils Multiple host interfaces 5 and 3 wires SPI, UART I,V bit stream available to host controller for customer own processing Case removal and Neutral Anti-tamper detection Exceeds 50-60Hz EN 50470-x, IEC 62053-2x, ANSI12.2x Applications Lighting, System Monitoring, Power Management, Consumer Electronics, Metering Product Information IC Function: Single Phase Energy Metering Supply Voltage Min: 2.95V Supply Voltage Max: 3.65V IC Package Type: QFN No. of Pins: 32Pins Operating Temperature Min: -40°C Operating Temperature Max: 85°C Product Range: - MSL: MSL 3 - 168 hours
