Microchip PAC1932T-I/JQ, Current Monitor 16-Pin, UQFN

The PAC1932/3/4 are two, three and four-channel power and energy monitoring devices. 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. This enables energy monitoring with integration periods from 1 ms up to 36 hours or longer. Bus voltage, sense resistor voltage and accumulated proportional power are stored in registers for retrieval by the system master or Embedded Controller.High-Side Current Monitor with 2, 3 or 4 Channels 100 mV full scale range for current sense voltage,16 bit resolution Selectable bidirectional current sense capability, -100 mV to +100 mV range, 16 bit two’s complement (signed) data format External sense resistor sets full scale current range Very low input current simplifies routing Wide Bus Voltage Range for Voltage Monitor 0V to 32V input common-mode voltage
