Abstract

See full text

An under voltage lockout circuit configured to set a minimum turn-on voltage for a load is provided. The circuit includes an input terminal configured to receive an input voltage. The circuit includes a first transistor configured to become conductive to supply the input voltage to the load when an input voltage to the under voltage lockout circuit exceeds a threshold, and a second transistor coupled to the first transistor, the second transistor configured to become conductive to supply the input voltage to a first resistor and not to the load when an input voltage to the under voltage lockout circuit falls below the threshold.
