Abstract
One example discloses a voltage select circuit, comprising: a first input configured to receive a first input voltage; a second input configured to receive a second input voltage; a first diode having a first polarity coupled to the first input; a second diode having a first polarity coupled to the second input; an output coupled to a second polarity of both the first and second diodes; a diode bypass circuit coupled to the first input and the output in parallel with the first diode, and coupled to the second input; and wherein the bypass circuit is configured to pass the first input voltage to the output if an absolute value of the second input voltage is less than a voltage drop of the second diode.
