Microchip Current Monitor 16-Pin Surface Mount UQFN Package PAC1932T-I/JQ

Microchip PAC1932T-I/JQ Current Monitor 16-Pin device with a UQFN surface mount package offers high-precision power and energy monitoring capabilities. It functions with a supply voltage range of 2.7V to 5.5V and is designed to operate reliably across a wide temperature range from -40°C up to 150°C, making it ideal for demanding industrial, automotive, and electronic applications.

This current monitor integrates a high-voltage multiplexer that sequentially connects inputs to a bus voltage monitor and current sense amplifier feeding into high-resolution 16-bit ADCs. The device allows selectable bidirectional current sensing across a ±100 mV range, providing signed output in two’s complement format. External sense resistors set the full-scale current range, allowing system designers flexible configuration options tailored to their measurement needs.

The PAC1932T series can monitor two, three, or four channels of power and energy data. It performs digital power calculations and energy accumulation with integration periods from 1 millisecond up to 36 hours or longer. Bus voltage, sense resistor voltage, and accumulated proportional power values are stored in registers for retrieval by a system master or embedded controller, enabling efficient power management and energy profiling in embedded systems.

The compact 4 mm length and 500 μm height UQFN package ensures a small footprint on printed circuit boards, suitable for space-constrained electronic designs. With RoHS compliance, this device meets environmental standards important to modern electronics manufacturing.

Common applications include industrial power monitoring, energy metering, automotive system monitoring, embedded control systems, telecommunications power supplies, and laboratory instrumentation. Its high resolution and wide common-mode voltage range make it suitable for accurate current measurement and power monitoring in complex electronic systems.
