Part Number: INA299-Q1 Hello TI
Im using INA299A1QDBVRQ1 current amplifier in my BMS board , i want the bidirectional measurement for charge and discharge current. so i have input of 3.3V so
if the input is Vs = 3.3V , what should the voltage applied…
Lukas,
The current sense can be ground side because VCM of the INA299 includes ground. Resistor dividing the 400V then buffering will help with VBUS impedance. Voltage is scaled so the power reading will be scaled the same.
