3.1.5 Current Measurement

Two Microchip DC power/energy monitors are embedded on the SAM9X60-EK board:

• one single high-side current sense monitor PAC1710

• one four-channel current sense monitor PAC1934

Both chips communicate with the MPU via a Two-wire Interface (TWI) and both output their ALERT# signal to a port

expander.

The PAC1710 is a single high-side bidirectional current sensing monitor with precision voltage measurement

capabilities. The power monitor measures the voltage developed across an external sense resistor to represent the

high-side current of a battery or voltage regulator. The PAC1710 also measures the SENSE+ pin voltage and

calculates average power over the integration period. The PAC1710 can be programmed to assert the ALERT# pin

when high and low limits are exceeded for current sense and bus voltage. For more information about the PAC1710,

refer to the product .web page

One current sense resistor is populated on board for measuring voltage and current on the main 5V power rail.

The PAC1934 is a four-channel power/energy monitor with current sensor amplifier and bus voltage monitors that

feed high resolution ADCs. Digital circuitry performs power calculations and energy accumulation. The PAC1934

enables energy monitoring with integration periods from 1 ms to up to 36 hours. Bus voltage, sense resistor voltage,

and accumulated proportional power are stored in registers for retrieval by the system master or embedded

controller. For more information about the PAC1934, refer to the product .web page
