Figure 16. Active Glitch/Power Filter
When the internal power/glitch filter is not used, both V
must be connected together externally to the power supply.
When the internal circuitry is used, the V
power supply and the V
age capacitor (1
power supply glitches.
Table 8 describes the active glitch/filter specifications.
Table 8. Active Glitch/Filter Specifications (Preliminary)
On the wafer level, all three power buses are available. Depending on the number
of pins of the package, one or more power buses are connected together.
The active glitch/power filter effectively increases the noise immunity for battery-
operated designs where the controller is driving high current loads (for example,
IR LED).
