CONTROL PIN CHARACTERISTICS (Cont’d)
Figure 78. RESET pin
protection1)2)3)4)
1. The reset network protects the device against parasitic resets.
2. 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 (watchdog).
3. Whatever the reset source is (internal or external), the user must ensure that the level on the RESET pin can go below
the VIL max. level specified in Section 11.9.1 . Otherwise the reset will not be taken into account internally.
4. 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 or external reset circuit for example) is less than the ab-
solute maximum value specified for IINJ(RESET) in Section 11.2.2 on page 92.
