The 5 V supply is jumper selected to power VDD on the TPS2413s and the glitch circuit if the control voltage is less than 3 V. The Glitch maker, discussed in the test methods section of the User’s Guide, applies a 1 ohm load to the input supply for 1 ms. 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 TPS2413.
Texas Instruments TPS2413EVM
The TPS2413EVM is an evaluation module set up to wire-OR two power supplies for redundant power to a load using two TPS2413s and MOSFETs.
