Electrical characteristics

Tips when using the LVD

1. Check that all recommendations related to reset circuit have been applied (see RESET

circuit design recommendations)

2. Check that the power supply is properly decoupled (100nF + 10µF close to the MCU).

Refer to AN1709. If this cannot be done, it is recommended to put a 100 nF + 1M pull-

down on the RESET pin.

3. The capacitors connected on the RESET pin and also the power supply are key to

avoiding any start-up marginality. In most cases, steps 1 and 2 above are sufficient for a

robust solution. Otherwise: replace 10nF pull-down on the RESET pin with a 5 µF to

20 µF capacitor.
