Image of Microchip Technology's PAC195x Power Monitors Microchip Technology's PAC195X devices are one-, two-, three-, and four-channel energy monitors 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/undervoltage, over/undercurrent, and overpower against user-programmed limits for each channel and generate an ALERT when the threshold is exceeded.
