RN8302B

The RN8302B is a 3-phase energy metering IC with 64 pins (LQFP package). Key functions include:
- Energy Measurement: Accurate active, reactive, and apparent energy calculation.
- ADC Channels: 7-channel Σ-Δ ADCs for voltage/current sensing.
- Communication: Supports UART, SPI, and I²C interfaces.
- Tamper Detection: Includes anti-tamper features like reverse flow detection.
- Power Monitoring: Measures parameters like voltage, current, power factor, and frequency.
- On-Chip Features: Built-in temperature sensor, reference voltage, and real-time clock (RTC).
It’s widely used in smart meters and power monitoring systems.

The RN8302B is a metering IC primarily used in energy measurement applications. Key areas include:
1. Smart Meters – Single-phase and three-phase electricity meters for residential and industrial use.
2. Power Monitoring – Real-time energy consumption tracking in appliances and power systems.
3. Renewable Energy – Solar inverters and microgrid energy management.
4. Industrial Automation – Power quality analysis and load control.
5. EV Charging – Energy measurement in electric vehicle charging stations.
It supports accurate voltage, current, and power calculations with communication interfaces like SPI/UART for data transmission.

The RN8302B is typically available in a QFN-32 (Quad Flat No-lead, 32-pin) package. This compact, surface-mount design offers efficient thermal performance and space-saving benefits, suitable for energy metering applications. The package dimensions are usually around 5mm × 5mm with a low profile.
