PAC1941-1 Single/Multi-Channel Power Monitor

PAC1941-1 Single/Multi-Channel Power Monitor

The PAC194X products are one, two, three and four-channel energy monitors, with bus voltage monitors and current sense amplifiers that feed high-resolution ADCs. There are two versions of the PAC194X: the PAC194X-1 devices are for high-side current sensing and the PAC194X-2 devices are for low-side .

Features

• High-Side/Low-Side Current Monitor with One, Two, Three or Four Channels: - 100 mV Full-Scale Range (FSR) for current sense voltage - 16-bit resolution for current measurement - Programmable FSR: -50 mv to +50 mv - External sense resistor sets the full-scale current range - Very low input current simplifies routing
• Voltage Monitor with Wide VBUS Range - 0V to 9V FSR - 4.5V programmable VBUS option - 16-bit resolution for voltage measurements
• VSOURCE Can Be Applied before VDD Is Applied
• Real-Time Auto-Calibration of Offset Error for Voltage and Current
• 1% Power Measurement Accuracy ov.
