Microchip Technology's PAC1932T-I/JQ

The PAC1932T-I/JQ is a precision power and energy monitoring chip developed by Microchip Technology, a leader in microcontroller, mixed-signal, analog, and Flash-IP solutions. This innovative device is designed to accurately measure voltage, current, and power of supply rails that are as low as 0V and as high as 32V.

One of the key features of the PAC1932T-I/JQ is its ability to provide full-scale power measurement with an internal multiplication of voltage and current values, eliminating the need for an external microcontroller to perform calculations. This makes it an ideal solution for power consumption analysis and energy-saving applications across a wide range of industries, including consumer electronics, industrial control, and automotive systems.

The device is highly versatile and features two high-side current-sense amplifiers, which enable it to monitor two separate rails simultaneously. This dual-channel capability allows users to monitor power supply and system power consumption separately, if needed. The PAC1932T-I/JQ integrates a 16-bit analog-to-digital converter (ADC) for each channel, ensuring high-precision measurements. Additionally, it offers a one-shot measurement mode for capturing snapshot power measurements, as well as continuous monitoring mode for real-time analysis.

Communication with the PAC1932T-I/JQ is facilitated through an I2C interface, which is widely used in embedded systems for its simplicity and efficiency in connecting multiple devices. The product is available in a compact 20-pin QFN (quad flat no-lead) package, making it suitable for space-constrained applications.

Microchip Technology's PAC1932T-I/JQ is characterized by its low power consumption and high accuracy, making it an excellent choice for developers looking to enhance the energy efficiency of their products. It is also supported by Microchip's extensive technical resources, including datasheets, application notes, and customer support, ensuring a smooth integration into various designs.
