The NCP51810 high−speed, gate driver is designed to meet the

stringent requirements of driving enhancement mode (e−mode), high

electron mobility transistor (HEMT), gallium nitrade (GaN) power

switches in medium−voltage half−bridge DC−DC application. The

NCP51810 offers short and matched propagation delays with

advanced level shift technology providing −3.5 V to +150 V (typical)

common mode voltage range for the high−side drive and −3.5 V to

+3.5 V common mode voltage range for the low−side drive. In

addition, the device provides stable dV/dt operation rated up to 200

V/ns for both driver output stages in high speed switching

applications.

To fully protect the gate of the GaN power transistor against

excessive voltage stress, both drive stages employ a dedicated voltage

regulator to accurately maintain the gate−source drive signal

amplitude. The circuit actively regulates the driver’s bias rails and thus

protects against potential gate−source over−voltage under various

operating conditions.

The NCP51810 offers important protection functions such as

independent under−voltage lockout (UVLO), monitoring VDD bias

voltage and VDDH and VDDL driver bias and thermal shutdown

based on die junction temperature of the device. Programmable

dead−time control can be configured to prevent cross−conduction.
