Power and energy monitor feature integrated sense resistor

Three internal No Latency ΔΣ ADCs ensure accurate measurement of voltage and current, while high bandwidth analogue multiplication of voltage and current provides accurate power measurement in a wide range of applications.

An internal 300µΩ, temperature-compensated sense resistor minimises efficiency loss and external components. The differential voltage measurement range ranges from -0.3 to 15.5V, independent of supply voltage. All measured quantities are stored in internal registers accessible via the selectable I2C/SPI interface. Thresholds can be set for each parameter with an optional alert when a threshold is exceeded.
