Hello Ryker,

The INA228 and it's SPI equivalent, the INA229, are the only devices we have with Coulomb counting. The next best thing is Energy accumulation. Here are devices we have with Energy accumulation in case you are interested in checking them out:

INA228 & INA229
INA4235 & INA4230
INA700
INA740A &INA740B
INA745A &INA745B
INA780A & INA780B
INA233

Mitch

Hi Mitch,

Do we have Auto grade (48V Auto) and Operational current < 0.5mA devices? Thanks.

Hey Ryker,

No, we don't have any digital power monitors that fit those requirements. However, we do have some analog current sensors that fit those requirements: https://www.ti.com/amplifier-circuit/current-sense/products.html#1498=Automotive&726max=48%3B120&236max=0.03%3B0.5&
