The UCC272xx and UCC273xx devices are a family of high current half-bridge drivers optimized to drive MOSFETs and IGBTs in fast switching, high-powered environments across industrial and automotive applications. The family has over 15 generic parts, each with specific differences. This product overview highlights the benefits of all the offerings and aims to assist engineers in selecting the best driver.
Optimized
UCC272xx and UCC273xx features both 3A/3A and 3.7A/4.5A drive current options to reduce switching losses and improve overall efficiency in high-power systems. This drive capability paired with small package options, such as the 3mm × 3mm VSON, make the UCC272xx and UCC273xx family one of the most versatile families of half-bridges. The extensive GPNs and feature sets maintains that there is a good device for your application.
Features
The UCC273xx family extends the UCC272xx devices by offering input interlock and enable functionality. Input interlock is a logic function built in to prevent shoot-through events. If both the high-side and low-side of the half bridge were to output at the same time, current "shoots through" and cause damage to the transistor. Since power FETs are not cheap, interlock is offered as a preventative measure to save the board. Enable functionality is designed via an additional pin, and thus only offered in the 10-pin DRC orderable parts. If enable is sent low, then regardless of the input signal the IC receives, the driver is prevented from outputting. An extended benefit of this feature is that UCC273xx operates at a lower quiescent current when disabled, drawing a typical of only 3uA. This decreases the power drawn from your system and helps optimize efficiency in designs.
Robust
The UCC272xx and UCC273xx 120V VHB and -(28VDD)V negative transient handling allows the proper headroom and buffer for the driver to exist and operate in noisy environments without the need for external components. The integrated bootstrap diode is designed to handle fast-switching, high stress environments. As mentioned, interlock logic helps prevent damage to transistors which can be a significant cost on the board.
