•
The 5-V supply is used to power status LEDs. It is jumper selected to power VDD on the TPS2410s
and the glitch circuit if the control voltage is less than 3.0 V.
and the glitch circuit if the control voltage is less than 3.0 V.

status are displayed.
•
The Glitch maker, discussed in the Test Methods Section applies a 1-
Ω
load to the input supply for
100
μ
s. This disruption allows the user to scope test points and observe system recovery.
•
The RSET resistor is used to program the turn-off point of the TPS2411.
•
The Filter compensates for system noise.
•
The UV and OV circuits set permissible limits for input operating voltage.
