Reference Figure 2 , a block diagram of the HPA227.

• The 5-V supply is jumper selected to power V

on the TPS2412s and the glitch circuit if the control

voltage is less than 3.0 V.

• The Glitch maker, discussed in the Test Methods section applies a 1- Ω load to the input supply for 1

ms. This disruption allows the user to scope test points and observe system recovery.

• The R

SET

resistor is used to program the turn off point of the TPS2411.
