UCC27423DR +BOM

4-A/4-A dual-channel gate driver with 5-V UVLO, enable, and inverting inputs

UCC27423DR General Description

One standout feature of the UCC27423DR is its built-in shoot-through protection mechanism, which actively prevents the occurrence of simultaneous conduction in high-side and low-side MOSFETs. This proactive measure significantly reduces the risk of device malfunction and enhances overall system reliability. Moreover, the programmable dead-time control feature allows for fine-tuning of timing parameters, enabling precise management of MOSFET switching to avoid shoot-through incidents effectively
