PAC194x & PAC195x Monitors

Microchip Technology PAC194x and PAC195x Current and Power Monitors are a portfolio of one, two, three, or four-channel energy monitors. The monitors are bus voltage monitors and current sense amplifiers that feed high-resolution ADCs. There are two versions of the PAC195X. The PAC195X-1 devices are for high-side current sensing, and the PAC195X-2 devices are for low-side current sensing or floating VBUS applications.
