Figure 90. RESET pin protection when LVD is disabled
1. The reset network protects the device against parasitic resets.
2. Please refer to
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
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 is less than the absolute maximum value specified for
