In summary, Microchip Technology’s PAC194x and PAC195x multi-channel power monitors are a portfolio of one, two, three, or four-channel energy monitors. They are Bus voltage monitors and current sense amplifiers that feed high-resolution ADCs. There are two versions of each: the PAC194x-1 and PAC195x-1 devices for high-side current sensing, and the PAC194x-2 and PAC195x-2 devices for low-side current sensing or floating V_BUS applications.
