Symbol
- 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, illegal opcode 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
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 I
