Description
Manual Reset Input. When taken below 0.6 V, a RESET/RESET is generated. MR can be driven from TTL, CMOS
logic, or from a manual reset switch because it is internally debounced. An internal 70 μA pull-up current holds
the input high when floating.
Power Supply Input.
Ground. Ground reference for all signals (0 V).
Power-Fail Input. PFI is the noninverting input to the power-fail comparator. When PFI is less than 1.25 V, PFO
goes low. If unused, PFI should be connected to GND.
Power-Fail Output. PFO is the output from the power-fail comparator. It goes low when PFI is less than 1.25 V.
No Connect.
Logic Output. RESET goes low for 200 ms when triggered. It is triggered either by V
threshold or by a low signal on the MR input. RESET remains low whenever V
remains low for 200 ms after V
timeout does not trigger RESET unless WDO is connected to MR.
Logic Output. RESET is an active high output suitable for systems that use active high reset logic. It is the
inverse of RESET.
