hi,
i m using ucc3956 to charge 48V li ion battery
when i tested it i m getting some problems
i just gave Vcc and ground and checked voltage at CAO(pin 15). its giving around 4.1V
and Voltage at CA- (pin 16) is around 0.008V
but since the +ve terminal of op amp is tied to 2.05V this should also be 2.08V?
moreover i tried to check the trickle current after connecting necessary components. it doesn't give the required output (RG1/(7.5*Rset*rsense)
the current at the inverting terminal is also not 0.68/Rset as given in the datasheet.
Even after changing the IC i am getting the same issue
can anyone help me out in this.
