Microchip Current Monitor 16-Pin VQFN 2.7V to 5.5V Quiescent Current 5μA PAC1952T-2E/4MX

Microchip PAC1952T-2E/4MX is a sophisticated current monitor in a 16-pin VQFN package designed for industrial and embedded system applications requiring precise current and power measurement. It operates efficiently with a supply voltage ranging from 2.7V to 5.5V and draws a minimal quiescent current of 5μA, making it ideal for power-sensitive environments.

This device integrates four channels, each equipped with voltage and current sense amplifiers feeding high-resolution 16-bit ADCs, enabling accurate monitoring of bus voltage and current sensing. Its onboard digital circuitry performs power calculations and accumulates energy data with high precision, supporting integration periods lasting up to a year or longer to facilitate comprehensive energy tracking.

The PAC1952T-2E/4MX offers user-programmable digital comparators that monitor over/under voltage, over/under current, and overpower conditions for each channel, generating ALERT signals when thresholds are exceeded. This feature is valuable for system protection and fault detection in applications such as cloud computing, notebook and tablet computing, optical networking modules, and high-performance computing platforms.

With a high-speed communication capability of up to 3.4 Mbps in burst mode, it ensures efficient data transfer to host controllers. The device supports surface mount technology via a 16-pin very thin quad flat no-lead (VQFN) package, enabling compact circuit board designs beneficial in dense electronic assemblies.

The operating temperature range from -40°C to 150°C suits harsh industrial environments, assuring reliable performance in diverse conditions. Its external sense resistor configuration allows flexible full-scale current range adjustments, and the device requires no input filters, simplifying system design.

Key specifications include a voltage monitor with a wide VBUS range of 0V to 32V full-scale, 100 mV full-scale range for current sense voltage, and 1% power measurement accuracy over a broad dynamic range. It is RoHS compliant and designed for new condition deployments.
