11 / 15 page SOT23, Low-Power µP Supervisory Circuits with Battery Backup and Chip-Enable Gating ______________________________________________________________________________________ 11 watchdog is set low in the beginning of the program, set high at the beginning of every subroutine or loop, and set low again when the program returns to the beginning. If the program should hang in any subrou- tine, the problem would be quickly corrected. Replacing the Backup Battery When VCC is above VTH, the backup power source can be removed without danger of triggering a reset pulse. The device does not enter battery-backup mode when VCC stays above the reset threshold voltage. Negative-Going VCC Transients These supervisors are relatively immune to short-dura- tion, negative-going VCC transients. Resetting the µP when VCC experiences only small glitches is usually not desirable. The Typical Operating Characteristics section has a Maximum Transient Duration vs. Reset Threshold Overdrive graph for which reset is not asserted. The graph was produced using negative-going VCC pulses, starting at VCC and ending below the reset threshold by the magnitude indicated (reset threshold overdrive). The graph shows the maximum pulse width that a neg- ative-going VCC transient can typically have without triggering a reset pulse. As the amplitude of the tran- sient increases (i.e., goes further below the reset threshold), the maximum allowable pulse width decreases. Typically, a VCC transient that goes 100mV below the reset threshold and lasts for 30µs will not trig- ger a reset pulse. A 0.1µF bypass capacitor mounted close to the VCC pin provides additional transient immunity.
