TS823/824/825 Series
Microprocessor Supervisory Circuit
with Watchdog Timer & Manual Reset
1/8
Version: B07
SOT-25
General Description
The TS823/824/825 family allows the user to customize the CPU monitoring function without any external
components. The user has a large choice of reset voltage thresholds and output driver configurations, all of which are
present ant the factory. Each wafer is trimmed to the customer’s specifications.
These circuits will ignore fast negative going transients on Vdd. The state of the reset output is guaranteed to be
correct down to 1V. After Vdd crosses above a factory present threshold, the TS823/824/825 assert a reset signal.
After a predetermined time (the “reset” interval) the reset is deasserted. If Vdd ever drops below the threshold voltage
a reset is asserted immediately. In addition to a supply monitoring function the TS823/824/825 also monitor transitions
at the watchdog (WDI) input. If a logic transition does not occur at the WDI pin within a certain time interval (the
“watchdog” interval) then a reset is asserted. The reset deasserts after the reset interval, as explained earlier.
The TS823/824/825 can both assert a reset manually by pulling the MR input to ground, and the micro-power
quiescent current make this family a natural for portable battery powered equipment.
