RESET pin protection when LVD is disabled
When the LVD is disabled, it is recommended to protect the RESET pin as shown in

Figure 79. RESET pin protection when LVD is disabled
The reset network protects the device against parasitic resets.
The output of the external reset circuit must have an open-drain output to drive the ST7
reset pad. Otherwise the device can be damaged when the ST7 generates an internal
reset (LVD or watchdog).
Whatever the reset source is (internal or external), the user must ensure that the level
on the RESET pin can go below the V
Otherwise the reset will not be taken into account internally.
Because the reset circuit is designed to allow the internal RESET to be output in the
RESET pin, the user must ensure that the current sunk on the RESET pin (by an
external pull-up for example) is less than the absolute maximum value specified for
