TS823/824/825

2003/12 rev. A
Detail Description (continued)
Watchdog Input Current
The watchdog input pin (WDI) typically sources/sinks
8uA when driven high or low. So from a power
dissipation point of view the duty cycle of the waveform
at WDI is unimportant. When the WDI pin is floating or
tri-stated the power supply current fall to less than 3uA.
Glitch Rejection
The TS823/824/825 family will reject negative going
transients on the Vdd line to some extent. The smaller
the duration of the transient the larger its amplitude may
be without triggering a reset. The “Glitch Rejection”
chart in the graphs section of this datasheet shows the
relation between glitch amplitude and allowable glitch
duration to avoid unintended resets.
Accurate Output State at Low Vdd
With Vdd voltage on the order of the MOS transistor
threshold (<1V) the outputs of the TS823/824/825 may
become undefined. For parts with active low output
RESET a resistor placed between RESET and Gnd on
the order of 100K
will ensure that the RESET output
stays low when Vdd is lower than the threshold voltage
of the part. In a like manner a resistor on the order of
100K
when placed between (RESET) and Vdd will
ensure parts with active high output (RESET) will remain
high when Vdd is lower than the threshold voltage of the
parts.
