Microchip PAC1952T-2E/4MX, Current Monitor 16-Pin, VQFN

The Microchip Technology PAC1952T-1E/J6CX 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.
