VZC: Voltage zero crossing 0. OCF: Overcurrent fault 1. OVRMS: The VRMS overvoltage flag 1. UVRMS: The VRMS undervoltage flag 2. UVRMS: The VRMS undervoltage flag 2. OVRMS: The VRMS overvoltage flag 3. The OR of OVRMS and UVRMS (if either flag is triggered, 3. The OR of OVRMS, UVRMS, and OCF_LAT [Latched the DIO_0 pin will be asserted) Overcurrent fault] (if any of the three flags are triggered, the DIO_1 pin will be asserted) VZCDIO_0OVRMSDIO_0 / MOSIMOSIUVRMSDIO_0_Sel[0..1]Comm_SelOCFDIO_1UVRMSDIO_1 / CSOVRMSCSOCF_LATDIO_1_Sel[0..1]Comm_Sel Allegro MicroSystems, LLC 5 955 Perimeter Road Manchester, NH 03103-3353 U.S.A. www.allegromicro.com Document Outline Features and Benefits Description Package Typical Application Selection Guide Absolute Maximum Ratings Isolation Characteristics Thermal Characteristics Functional Block Diagram Pinout Diagram and Terminal List Digital I/O Electrical Characteristics Data Acquisition ADCs Raw Signal Sensitivity and Offset Trim Phase Compensation Zero Crossing Power Calculations Digital Communication Registers and EEPROM EEPROM Error Checking and Correction (ECC) Memory Map Volatile Memory Map Application Connections Recommended PCB Layout Package Outline Drawing
