Abstract
A driving output circuit, a chip, and a driving output method are provided; the driving output circuit includes: a timer for outputting a timing signal; a bootstrap module for generating a first turn-on voltage based on an input signal; a charge pump for generating a second turn-on voltage based on the timing signal; a driving module including an upper driving MOSFET and a lower driving MOSFET connected to the upper driving MOSFET, and the upper driving MOSFET is connected to the lower driving MOSFET at a signal output; the first turn-on voltage and the second turn-on voltage are both used to turn on the upper driving MOSFET and/or the lower driving MOSFET to cause the signal output to output an output signal. The present disclosure provides a dynamic hybrid driving output circuit, which has improved gate oxide reliability and an enhanced anti-leakage function when not powered.
