ABSTRACT:
A programmable detection adjuster is disclosed. The programmable detection adjuster comprises a bandgap and an adjusting circuit. The bandgap comprises a power input terminal, a voltage output terminal, a main resistance and a plurality of resistors. The adjusting circuit comprises a plurality of adjusting resistors, a plurality of transistor switches, a logic controller and detection circuits; said adjusting resistors connected to the main resistance of the bandgap in series. The adjusting resistors are respectively connected to the transistor switch in parallel. The transistor switches are connected to the logic controller. The logic controller is respectively connected to the detection circuits. The detection circuit detects the corresponding resistances in the detection circuit and outputs a voltage level to the logic controller to enable the logic controller to control a conduction of the transistor switches according to a logic conversion table.
