JAJSDC3A June 2017 – August 2018 UCC27712
PRODUCTION DATA.
UCC27712 features separate inputs, HI and LI, for controlling the state of the outputs, HO and LO, respectively. The device does include internal cross-conduction prevention logic and does not allow both HO and LO outputs to be turned on simultaneously (refer to Table 3). This feature prevents cross conduction in bridge topologies in the case of incorrect timing from the controller.
