Microchip PAC195x Single-Multi-Channel Power Monitor
With Accumulator, 32V Full-Scale Range
Microchip PAC195X is a series of energy monitors – one, two, three and four-channel with bus voltage monitors and current sense amplifiers – that feed high-resolution ADCs.
There are two versions of the PAC195X family: PAC195X-1 devices are for high-side current sensing and PAC195X-2 devices are for low-side current sensing. PAC195X devices have a set of digital comparators that allow the user to detect over/under voltage, over/under current and overpower against user-programmed limits for each channel and generate an alert when the threshold is exceeded.

Evaluation Board DT100119
For PAC1954 4 CH High Side DC Power Monitor
This board enables easy connection of the PAC1954 to power sources and loads for power monitoring and energy metering using on board 4mOhm high side current sensing resistors. It has USB connection to PC and a GUI to display the data, as well as options to disconnect the PC and communicate directly with a different host controller. Measurement channels 1,2 and 3 are pre-populated to show demo currents and they can be switched to the external input sense resistors by moving two 0 Ohm resistors on each channel.
