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.
