Microchip Technology PAC1932, PAC1933, and PAC1934 Power Monitor ICs (PMICs) are multi-channel power and energy monitoring devices. The PAC1932 is a dual-channel power and energy monitor, the PAC1933T-I/JQ features three channels, and the PAC1934 is a quad-channel power monitor. A high-voltage multiplexer sequentially connects the inputs to a bus voltage monitor and current sense amplifier that feed high-resolution ADCs. Digital circuitry performs power calculations and energy accumulation.
