Feature Description (continued)
The frame, D, shows a typical PGOOD, high to low transition. As soon as PGOOD is low, the internal oscillator is
powered OFF and the digital output pins, TCAL, RSTn, and WAKE, are asynchronously reset by the falling edge
of the PGOOD signal, such that TCAL and WAKE reset at low logical values, while RSTn resets at a high logical
value.

8.3.1.3 Watchdog Feature
Most of the microcontroller-based systems need to be self-reliant; if the software hangs for any reason, the
microcontroller must be reset. The TPL5000 can provide this functionality by connecting a microcontroller
programmable output pin to the DONE input pin. If the DONE line does not toggle within the selected delay
period, then the microcontroller is not operating properly and must be reset.
The TPL5000 recognizes a valid DONE signal as a low to high transition; if two DONE signals are received
within the delay period the second signal is ignored.
In the TPL5000, the watchdog window and the delay period are equivalent. A valid "DONE" signal resets the
watchdog counter only, and not the delay time counter. A PGOOD low to high transition clears both the
watchdog and delay time counters.
Figure 6 shows the watchdog feature of the TPL5000. The sequence A, B, C is a standard sequence with the
microcontroller working properly. In this normal sequence, the microcontroller sends a valid "DONE" (arrow B)
before the end of the delay period. The sequence C, D ,E is an anomalous sequence in which the microcontroller
is not in a valid state, and it does not send the DONE signal (dashed pulse) before the end of the delay period.
The TPL5000 determines the microcontroller is hung and sends a RESET signal (arrow E) when the period delay
has elapsed.
8.3.1.4 Different Utilizations of the TPL5000
When either the watchdog or the supervisor feature of the TPL5000 are not required, it is possible to disable
them reducing the interconnections between the TPL5000 and the microcontroller.
Connecting the DONE pin either to GND or to TCAL pin disables the watchdog feature. If connected to GND, the
TPL5000 only sends a reset pulse when the time delay elapses. If DONE is connected to TCAL, the TPL5000
sends out just one RESET pulse after a PGOOD low to high transition, when the time delay elapses and then
WAKE pulses when the successive time delay elapses.
Connecting the PGOOD pin to the supply pin of the TPL5000 disables the supervisor feature.
