CS5462-IS

The CS5462-IS is designed as a low cost power meter solution conbinating two analog-to-digital converters (ADC), an energy to frequency converter, and energy pulse outputs on a single chip. It is designed to accurately measure and calculate energy for single phase2- or 3-wire power metering applications with minimal external components.

CS5462-IS has many features. (1)Single chip, power measurement solution. (2)Energy data linerity +/-0.1% of reading over 1000:1 dynamic range. (3)On-chip functions: measures energy and performs energy-to-pulse conversions. (4)Meets accuracy spec for IEC 687/1036. (5)On-chip system calibration option. (6)High pass filter option for both I and V. (7)2 available current input ranges. (8)On-chip 2.5V reference 25ppm/°C typ. (9)Pulse outputs for stepper motor or mechanical counter. (10)Ground reference input signals with single supply. (11)High frequency output for calibration. (12)On-chip power-on reset. And so on.

Some absolute maximum ratings of CS5462-IS have been concluded into several points as follow. (1)Its DC power supplies would be min -0.3V and max +6.0V for positive digital and it would be min -0.3V and max +6.0V for positive analog. (2)Its input current any pin except supplies would be max +/-10mA. (3)Its power dissipation would be max 500mW. (4)Its analog input voltage would be min -0.3V to (VA+)+0.3V. (5)Its digital input voltage would be min -0.3V and max (VD+)+0.3V. (6)Its ambient operating temperature range would be from -40°C to 85°C. (7)Its storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some DC electrical characteristics of CS5462-IS are concluded as follow. (1)Its high level input voltage would be min (VD+)-0.5V for XIN. (2)Its low level input voltage would be max 1.5V for XIN, Vdd=5V and it would be max 0.3V for XIN, Vdd=3.3V. (3)Its high level output voltage would be min (VD+)-1.0V. (4)Its low level output voltage would be max 0.4V. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
