Auto-reset circuit with improved testability

摘要

A first active element (41) has its first terminal coupled to a first power-supply terminal (31), its second terminal coupled through a resistor (51) to a second power-supply terminal (32), and its third terminal coupled to the second power-supply terminal (32), or to a control signal input terminal that is normally at the same potential as the second power-supply terminal (32). A second active element (42) has its first terminal coupled to the second power-supply terminal (32), its second terminal coupled through a resistor (52) to the first power-supply terminal (31), and its third terminal coupled to the second terminal of the first active element (41). A reset signal is taken from the second terminal of the second active element (42). The control signal can be used to prevent current flow during static current measurements.
