Dear
We are using your TPS65051 in an own design following all your documentation. We have a doubt related to document SLVA403, "Powering the Freescale™ i.MX25 Using the TPS65051".
The problem is with RESET circuit. In page 6 of the application note, using the corresponding calculations and values of resistors you provided (R5=237k, R6=3.01k, R15=180k), VH=2,3V and VL=2,26V which is not a possible value if voltage to these resistors is VLDO4 (in that case 1.6V).
We are not sure if these calculations are incorrect or we are missunderstanding something.
