Hi Team,
I plan use TI device implement CSM & protection function. Could provide your suggestion for me? thanks.
Test condition
Accuracy 5% - 10% @Light load 500mA
Accuracy 2% - 5% @Heavy load 45A (peak load transient 75A)
Bus Voltage 4.5VDC - 7VDC
1. Looks INA240 with shunt resistor 1m ohm have good performance. Am I right?
2. In my system, current is dynamic load since we have PWM control LED panel. so input current behavior is not average.
we need RMS converter DC out for MCU implement protect. such as ADI device AD8436 & AD637 has RMS to DC function.
