Thanks for your reply.It's for make a battery tester using different currents for different kind of batteries, drawing the discharge curve, calculating capacity and disconnecting when the battery voltage reaches the minimum voltage programmed.

Hello, I see in AN4899 some things:The diode marked in red in figure 1 prevents higher voltages than VDD+0.6V on a TT pin. For this reason, my design is not possible in TT pins.The NMOS marked in red in figure 2 has to withstand 12V (VDS) when is off...
