INA237 is a functionally equivalent variant of INA238 with slightly

different accuracy. INA228 is another variant of INA238 with higher ADC

resolution. This chip also reports the energy.



SQ52206 is a mostly compatible chip from Sylergy. It reports the energy

as well as the peak power consumption.
