MCP39F501T-E/MQ Microchip

MCP39F501 Single-Phase, Power-Monitoring IC with Calculation and Event Detection Features: Description: Power Monitoring Accuracy capable of 0.1% error The MCP39F501 is a highly integrated, single-phase across 4000:1 dynamic range power-monitoring IC designed for real-time measurement of input power for AC/DC power Fast Calibration Routines supplies, power distribution units and industrial Programmable Event Notifications such as over- applications. It includes dual-channel delta sigma current and voltage sag, surge protection ADCs, a 16-bit calculation engine, EEPROM and a 512 bytes User-accessible EEPROM through flexible 2-wire interface. An integrated low-drift voltage page read/write commands reference with 10ppm/C in addition to 94.5dB of Non-volatile On-chip Memory, no external SINAD performance on each measurement channel memory required allows for better than 0.1% accurate designs across a Built-in calculations on fast 16-bit processing core 4000:1 dynamic range. - Active, Reactive and Apparent Power Package Type - True RMS Current, RMS Voltage MCP39F501 - Line Frequency, Power Factor 5x5 QFN* Two-Wire Serial Protocol using a 2-wire Universal Asynchronous Receiver/Transmitter (UART) inter- face supporting multiple devices on a single bus 28 27 26 25 24 23 22 Low-Drift Internal Voltage Reference, 10 ppm/C MODE/DIR 1 A 21 GND typical 2 AN IN/DIO2 NC 20 28-lead 5x5 QFN package NC 3 19 V1+ Extended Temperature Range -40C to +125C EP UART RX 4 18 V1- 29 COMMON 5 Applications: A 17 I1- OSCI 6 16 I1+ Real-time Measurement of Input Power for AC/DC supplies OSCO 15 A1/DIO1 7 Intelligent Power Distribution Units 89 10 11 12 13 14 * Includes Exposed Thermal Pad (EP) see Table 3-1.
