Seoul, June 10, 2015 – Microchip Technology (Korea Representative: Byung-Don Han), a global leader in microcontroller, mixed-signal, analog, and Flash-IP solutions, announced the launch of the PAC1921, which combines analog and digital current sensors, at Sensors Expo. This new product is the world's first high-side current sensor to provide a configurable analog output capable of delivering power, current, or voltage information through a single output pin, alongside a digital output. Simultaneously, all power-related output values are available via a 2-wire digital bus that is compatible with the I2C™ interface. The PAC1921 is available in a 10-lead 3 x 3 mm VDFN package and is designed based on a 2-wire bus to maximize data and diagnostic reporting performance, featuring an analog output that minimizes data latency. Additionally, the analog output can be adjusted for use with 3V, 2V, 1.5V, and 1V microcontroller inputs.

The PAC1921 is suitable for networking, power distribution, power supplies, computing, and industrial automation applications where latency is unacceptable during high-speed power management. With a 39-bit accumulator and 128x gain configuration, it can be used for both heavy and light load power measurements ranging from 0V to 32V. Additionally, this device can integrate power consumption data for more than 2 seconds. In addition, the PAC1921 provides a READ/INT pin that allows the host to control the measurement cycle, and this pin can be used to synchronize readings from multiple devices.

Bryan J. Liddiard, Vice President of Marketing at Microchip’s Analog and Interface Products business unit, stated, “This product offers designers unique flexibility by featuring the ability to output power measurements in both digital and analog domains. The PAC1921 achieved this result through the combination of a digital current sensor that maximizes data and diagnostic reporting performance and an analog current sensor that minimizes data latency.”
