LM5108DRCR is a high frequency half-bridge gate driver with maximum switch node (HS) voltage rating of 100 V. LM5108DRCR allows for two N-channel MOSFETs to be controlled in half-bridge configuration based topologies such as synchronous buck, full bridge, active clamp forward, LLC, and synchronous boost.

LM5108DRCR has interlock functionality which, prevents both outputs from being high at the same time, in the case when both of the inputs are high. Battery powered tools can also use enable feature of the LM5108DRCR to reduce the standby current as well as to respond to system fault. The inputs are independent of supply voltage and can have independent pulse width.

LM5108DRCR——The low-side and the high-side outputs are matched to 1-ns between the turn-on and turn-off of each other. This allows for dead-time optimization which in-turn improves efficiency. 5-V UVLO allows the driver to operate at lower bias supplies which further allows the power stage to operate at higher switching frequency without increasing switching losses. VDD and HB UVLO threshold specifications are designed in such as way that both the high-side and low-side driver turns on typically at 5 V.
