7.2.2.3 FLT, RDY, and RST/EN Pin Circuitry
Both FLT and RDY pin are open-drain output. The RST/EN pin has 100kΩ internal pulldown resistor, so the driver is in OFF status if the RST/EN pin is not pulled up externally. A 5kΩ resistor can be used as pullup resistor for the FLT and RDY pins.
To improve the noise immunity due to the parasitic coupling and common mode noise, low pass filters can be added between the FLT, RDY, and RST/EN pins and the microcontroller. A filter capacitor between 100pF to 300pF can be added.
