Undervoltage Timing with Overvoltage Glitch
In Figure 11, both UV and OV pins are connected together.
When UV clears V
cycle starts. If the system bus voltage overshoots V
as shown at time point 2, TIMER discharges. At time point
3, the supply voltage recovers and drops below the V
– V
followed by a GATE start-up cycle.
