Datasheet Allegro ACS71020

ACS71020
Single Phase, Isolated, Power Monitoring IC
with Voltage Zero Crossing and Overcurrent Detection
DESCRIPTION FEATURES AND BENEFITS • Accurate power monitoring of AC/DC applications
• Reinforced isolation up to 517 VRMS in a single package
eliminates the need for dual isolated supplies (certification
pending)
• Active, reactive, and apparent power measurements, and
power factor
• RMS and instantaneous voltage and current measurements
• 0.85 mΩ primary conductor resistance for low power loss
and high inrush current withstand capability
• Dedicated voltage zero crossing pin
• Overcurrent fault output pin
• Hall-effect-based current measurement with commonmode stray field rejection
• User-programmable VRMS under/overvoltage pin
• 1 kHz bandwidth
• Current-sensing range from 0 to 90 A
• I2C or SPI communication
• User-programmable through EEPROM registers
• 16-bit voltage and current ADCs PACKAGE 16-pin SOICW (suffix MA) The sensor features all key power measurements, which can
be read out through I2C or SPI, as well as dedicated pins for
voltage zero crossing (suitable for light-dimming applications) …
