PAC195X Single/Multi-Channel Power Monitor with Accumulator, 32V Full-Scale Range Features Applications High-Side/Low-Side Current Monitor with One, Embedded Computing Two, Three or Four Channels: Networking - 100 mV Full-Scale Range (FSR) for current FPGA Systems sense voltage Low-Voltage/High-Power AI, GPU - Programmable FSR: -50 mv to +50 mv Industrial - 16-bit resolution for current measurements Linux Applications - External sense resistor sets the full-scale Notebook and Tablet Computing current range Cloud, Linux and Server Computing - Very low input current simplifies routing Optical Networking Modules Voltage Monitor with Wide V Range BUS - 0V to 32V FSR Computing Platform Support - 16V programmable V option BUS Windows 10 Driver - 16-bit resolution for voltage measurements Arduino Library V Can Be Applied before V Is Applied SOURCE DD Python Script Real-Time Auto-Calibration of Offset Error for MCC Library Voltage and Current 1% Power Measurement Accuracy over a Wide Description Dynamic Range On-Chip Accumulation of 30-bit Power Results for The PAC195X products are one, two, three and Energy Measurement four-channel energy monitors, with bus voltage - User programmable sampling rates of 8, 64, monitors and current sense amplifiers that feed 256 and 1024 SPS high-resolution ADCs. There are two versions of the PAC195X: the PAC195X-1 devices are for high-side - 5120 SPS for a single channel in Burst mode current sensing and the PAC195X-2 devices are for 2.7V to 5.5V Supply Operation low-side current sensing or floating VBUS applications. 2 - 1.62-5.5V capable I C/SMBus and digital I/O 2 Digital circuitry performs power calculations and - SMBus 3.1 and I C Fast Mode Plus, 1 Mbps energy accumulation. This enables energy monitoring - High-Speed mode (3.4 Mbps) with integration periods up to one year or longer. Bus SMBus Address 16 Options, Set with Resistor voltage, sense resistor voltage and accumulated ALERT Features that Can Be Enabled: proportional power are stored in registers for retrieval - ALERT on conversion complete by the system host or embedded controller. The PAC195X devices have a set of digital comparators - ALERT on Over/Undervoltage and Current or that allow the user to detect over/undervoltage, Overpower conditions over/undercurrent and overpower against user Coulomb Counting: When Selected, the programmed limits for each channel and generate an Accumulator Accumulates V Values. SENSE ALERT when the threshold is exceeded. 8X Averaging Mode for Single-Shot The sampling rate and energy integration period can be Measurements to Reduce Noise and Offset 2 controlled over SMBus or I C. Active channel selection, Two Independent ALERT/GPIO pins single-shot measurements and other controls are also Available Packages 2 configurable by the SMBus or I C. The PAC195X - 3 x 3 mm 16-Lead VQFN with wettable flanks device family uses real-time calibration to minimize the - 2.225 x 2.17 mm 16-Lead WLCSP offset error. No input filters are required for this device. 2021-2022 Microchip Technology Inc. and its subsidiaries DS20006539B-page 1PAC195X Package Types PAC195X-1 PAC195X-1 3x3mm VQFN* 2.225 x 2.17 mm WLCSP 12 3 4 A SENSE2+ SENSE1- SENSE1+ V DD 1 12 SLOW/ALERT1 SENSE1- B V 2 11 SENSE1+ DD SENSE2- GPIO/ALERT2 PWRDN GND EP GND 3 10 SENSE4+ 4 9 SCL SENSE4- C SENSE3- ADDRSEL SLOW/ALERT1 SCL D SENSE3+ SENSE4- SENSE4+ SDA PAC195X-2 PAC195X-2 3x3mm VQFN* 2.225 x 2.17 mm WLCSP 12 3 4 A VBUS1+ SENSE1- SENSE1+ V DD 1 12 SLOW/ALERT1 SENSE1- B V 2 11 SENSE1+ DD V BUS1- GPIO/ALERT2 PWRDN GND EP GND 3 10 SENSE2+ SCL 4 9 SENSE2- C V ADDRSEL SLOW/ALERT1 SCL BUS2- D V SENSE2- SENSE2+ SDA BUS2+ *Includes Exposed Thermal Pad see Table 3-1 and Table 3-2.
