Abstract
The present disclosure relates to a high voltage bidirectional power switch circuit that includes a high voltage block coupled to a first terminal; and a resistance network including modules connected in parallel with each other between the high voltage block and a second terminal. Each module includes a precision resistor connected in series with a conduction channel of a resistance switching transistor; a first biasing resistor connected between a first conduction channel terminal and a control terminal of the resistance switching transistor; a second biasing resistor connected between a second conduction channel terminal and the control terminal; a body bias control circuit configured to control a bias of body diodes of the resistance switching transistor; a switchable sourcing current source; and a switchable sinking current source. Switches of the switchable sourcing current source and the switchable sinking current source receive switching signals to control the resistance switching transistor.
