The Microchip Technology PAC1944T-E/4MX is a four-channel, 16 pin energy monitor with bus voltage monitor and current sense amplifier that feed high-resolution ADCs. It has a digital circuitry that performs power calculations and energy accumulation. This enables energy monitoring with integration periods up to one year or longer. The bus voltage, sense resistor voltage and accumulated proportional power are stored in registers for retrieval by the system host or embedded controller. This device has a set of digital comparators that allow the user to detect over/under voltage, over/undercurrent and overpower against user programmed limits for each channel and generates an ALERT when the threshold is exceeded. It is used in applications such as embedded computing, networking, Low voltage/high-power - AI, GPU, Linux® applications, notebook and tablet computing, cloud, Linux & server computing and optical networking modules.

100 mV full-scale range (FSR) for current sense voltage

16-bit resolution for voltage and current measurement

External sense resistor sets the full-scale current range

Very low input current simplifies routing

Voltage monitor with Wide VBUS Range

0V to 16V FSR

4.5V programmable VBUS option

VSOURCE can be applied before VDD is applied

1% power measurement accuracy over a wide dynamic range

On-chip accumulation of 30-bit power results for energy measurement

5120 SPS for a single channel in burst mode
