Microchip Current Monitor 16-Pin VQFN PAC1952T-2E/4MX 2.7V-5.5V 16-bit Resolution

Microchip PAC1952T-2E/4MX Current Monitor is a sophisticated 16-pin device housed in a VQFN package, offering high-precision current sensing and energy monitoring capabilities. It operates over a voltage supply range of 2.7V to 5.5V, suitable for embedded computing and networking applications.

This device features a 16-bit resolution ADC for both voltage and current measurements, enabling 1% power measurement accuracy over a wide dynamic range. It allows integration periods up to one year, providing robust energy accumulation for power monitoring systems.

The PAC1952T-2E/4MX includes digital comparators that detect over and under voltage, current, and power thresholds on four independent channels, generating ALERT signals when programmed limits are exceeded. It supports surface mount applications with a compact 3mm length VQFN package and utilizes real-time calibration to reduce offset error, eliminating the need for input filters.

Its external sense resistor sets the full-scale current range with a 100mV full-scale voltage, and it supports high-speed SPI interface communication at 3.4 Mbps. The device is designed to function within operating temperatures ranging from -40°C to 150°C, making it suitable for industrial, server, cloud computing, and AI/GPU hardware systems.
