Pin descriptions
Power supply (V
This pin is used to provide the power to the Smart Reset device and to monitor the power
supply. A 0.1 µF decoupling ceramic capacitor is recommended to be connected between
V
Ground (V
This is the ground for the device and all supplies.
Smart Reset inputs (SR0, SR1)
Push-button Smart Reset inputs. Both inputs need to be held active at the same time for at
least t
the unused one permanently to V
User-programmable Smart Reset delay (TSR pin)
Used to allow the user to program the setup time before the push-buttons action is validated
by reset output. Controlled by different voltage levels on the TSR pin: when connected to
ground, t
(all times are minimum). TSR is a DC-type input, intended to be either permanently
grounded, permanently connected to V
system glitch immunity it is strongly recommended to connect a 0.1 µF decoupling ceramic
capacitor between the TSR and V
Reset outputs (RST1, RST2)
Reset outputs, RST1 active-high, push-pull type, RST2 active-low, open-drain.
