7.2.2.3 FLT Output

FLT pin is an open-drain output. A 5-kΩ resistor can be used as pullup resistor for the FLT pins.

To improve the noise immunity due to the parasitic coupling and common mode noise, a low pass filter can be added between the FLT pin and the microcontroller. A filter capacitor between 100pF to 300pF can be added.
