Abstract
In described examples of a circuit that operates as a low-power ideal diode, and an IC chip that contains the ideal diode circuit, the circuit includes: a first P-channel transistor connected to receive an input voltage on a first terminal and to provide an output voltage on a second terminal; a first amplifier connected to receive the input voltage and the output voltage and to provide a first signal that dynamically biases a gate of the first P-channel transistor as a function of the voltage across the first P-channel transistor; and a second amplifier connected to receive the input voltage and the output voltage and to provide a second signal that acts to turn off the gate of the first P-channel transistor responsive to the input voltage being less than the output voltage.
