CS5460A Power Measurement Solution
A highly integrated solution for accurate power measurement in single phase power metering applications.
- Energy Data Linearity: ±0.1% of Reading over 1000:1 Dynamic Range
- On-Chip Functions: (Real) Energy, IV, IRMS and VRMS, Energy-to-Pulse Conversion
- Smart "Auto-boot" Mode: Enables Use without MCU
- AC or DC System Calibration
The CS5460A is a highly integrated power measurement solution that combines two Analog-to-digital Converters (ADCs), high-speed power calculation functions, and a serial interface on a single chip. It accurately measures and calculates Real (True) Energy, Instantaneous Power, IRMS, and VRMS for single phase 2- or 3-wire power metering applications.
The CS5460A interfaces with a low-cost shunt resistor or transformer to measure current, and with a resistive divider or potential transformer to measure voltage. It features a bi-directional serial interface for communication with a microcontroller and a pulse output engine where the average pulse frequency is proportional to the real power.
With on-chip functionality to facilitate AC or DC system-level calibration, the CS5460A's "Auto-boot" feature allows it to function stand-alone and initialize itself on system power-up. It reads calibration data and start-up instructions from an external EEPROM in Auto-boot Mode, enabling operation without a microcontroller to reduce costs.
- Power Dissipation: 500 mW
- Analog Input Voltage: (VA-) - 0.3V to (VA+) + 0.3V
- Digital Input Voltage: (DGND - 0.3V) to (VD+ + 0.3V)
- Ambient Operating Temperature: -40°C to 85°C
The CS5460A is designed with ground-referenced signals using a single supply, featuring on-chip 2.5V reference with drift of MAX 60 ppm/°C. The simple three-wire digital serial interface, watch dog timer, and power supply monitor enhance its usability in power measurement applications.
