... SOT23, Low-Power µP Supervisory Circuits with Battery Backup Detailed Description The Typical Operating Circuit shows a typical connection for the MAX6361–MAX6364 family. OUT powers the stat- ic random-access memory (SRAM). OUT is internally connected greater than the reset thresh old the greater of V ...

... R2 = 100kΩ, and calculate R1 = 273kΩ. A µP’s reset input starts the µ known state. The MAX6361–MAX6364 µP supervisory circuits assert a reset to prevent code-execution errors during power- up, power-down, and brownout conditions. RESET is guaranteed logic low or high depending on the device chosen (see Ordering Information ) ...

... SOT23, Low-Power µP Supervisory Circuits with Battery Backup Watchdog Software Considerations (MAX6362 Only) To help the watchdog timer monitor software execution more closely, set and reset the watchdog input at dif- ferent points in the program, rather than “pulsing” the watchdog input low-high-low. This technique avoids a “ ...
