FUNCTIONAL BLOCK DIAGRAM
Power Fail Detector
The power fail detector is a comparator in which the
inverting input is connected to the internal voltage reference,
the non-inverting input is the PFI pin of the TC3401 and the
PFO pin is the active low, open collector output. This
comparator is suitable as an early warning fail or low battery
indicator. In a typical application, where a voltage regulator
is being used to supply power to a system, the power fail
comparator would monitor the input voltage to the regulator
while the VDD monitor would measure the output voltage of
the regulator. Both PFO and RESET would drive interrupt
pins of a microcontroller.
The Power Fail detector, may be used as a Wake-up or
Watch-dog Timer. The
Typical Application Circuit on Page
1 shows an RC network on PFI with the capacitor tied to a
tri-stated
C I/O pin. If R4 is 1 M and C2 is 10F, the time
constant is roughly ten seconds. The
C resets the RC
network by driving the I/O tied to PFI low and then tri-stating
it. The RC network will ramp to 1.23V in roughly 9 seconds,
assuming a VBATT of 3.0V. With PFO tied to a C input or
interrupt, the
C will see a low-to-high transition on PFO
when voltage on PFI exceeds 1.23V. The PFO output is
guaranteed to be valid for VDD = 1.3 to 5.5V.
