General Description

The LMP92064 is a precision low-side digital current sensor and voltage monitor with a digital SPI interface.

This analog frontend (AFE) includes a precision current sense amplifier to measure a load current across a shunt resistor and a buffered voltage channel to measure the voltage supply of the load.

The current and voltage channels are sampled simultaneously by independent 125-kSps, 12-bit ADC converters, allowing for very accurate power calculations in unidirectional sensing applications.
