Dear All,
i am facing problem to design the following circuit
i have a hardware board with minimum operating voltage of 10.5 volts. The board is connected to a battery of 12v. In normal operations the 12v input is going to the hardware board but in some cases the battery voltage can fall upto 9v for some 10min and again comes back above 12V. So, under these conditions when the battery voltage is going below 10.5 volts i want to design a circuit such that when the battery voltage falls below 10.5 volts the new board should supply the required 10.5 volts and when the battery comes above 10.5v the battery should supply the voltage again. The new hardware to be designed should operate on the battery and even if the battery voltage going upto 9v the new board should supply 10.5 volts. Current rating is not a problem it requires only few millamps.
somebody please help me on this.
Thanks in advance,
regards
