... Dual/Triple, Ultra-Low-Voltage, SOT23 µP Supervisory Circuits Detailed Description The MAX6715A–MAX6729A/MAX6797A µP supervisory circuits maintain system integrity by alerting the µP to fault conditions. These ICs are optimized for systems that monitor two or three supply voltages. The output- reset state is guaranteed to remain valid while either ...

... MAX t RST RP Figure 2. Normal Watchdog Startup Sequence ______________________________________________________________________________________ Supervisory Circuits The MAX6715A–MAX6729A/MAX6797A are guaranteed to operate properly down to V that require valid reset levels down to V pulldown resistor at RST to ground. The resistor value used is not critical, but it must be large enough not to load the reset output when V old. For most applications, 100kΩ ...

... Dual/Triple, Ultra-Low-Voltage, SOT23 µP Supervisory Circuits Applications Information Interfacing to µPs with Bidirectional Most µPs with bidirectional reset pins can interface directly to open-drain RST output options. Systems simultaneously requiring a push-pull RST output and a bidirectional reset interface can be in logic contention. To prevent contention, connect a 4.7kΩ resistor between RST and the µ ...

... If the program should “hang” in any subroutine, the I/O is continually set low and the watchdog timer is allowed to time out, causing a reset or interrupt to be issued. ______________________________________________________________________________________ Supervisory Circuits START SET WDI HIGH PROGRAM CODE ...
