INA209 Datasheet (Texas Instruments) - Bi-Directional Current/Power Monitor

INA209, Bi-Directional Current/Power Monitor

The INA209 is a high-side current shunt and power monitor with an I2C interface.

The INA209 monitors both shunt drop and shunt bus voltage.

A programmable calibration value, combined with an internal multiplier, enables direct readouts in amperes.

An additional multiplying register calculates power
