The TD99102 from Teledyne e2v HiRel Electronics is a GaN Transistor Gate Driver that is designed to control the gates of external power devices such as GaN, HEMT, and power MOSFET. It requires an input voltage of 4-6.5 V for operation and provides switching transition speeds in the subnanosecond range for supporting switching applications of up to 20 MHz.  This gate driver is optimized for matched dead time and offers best-in-class propagation delay to improve system bandwidth. The dead-time controller allows the timing of the LS and HS gates to eliminate any large shoot-through currents that could dramatically reduce the efficiency of the circuit and potentially damage the transistors.

The TD99102 is manufactured using Peregrine’s UltraCMOS process, a patented advanced form of silicon-on-insulator (SOI) technology, offering the performance of GaAs with the economy and integration of conventional CMOS. It is available as a bumped flip chip die and is ideal for dc-dc conversions, ac-dc conversions, motor driver, and orbital point of load (POL) module power distribution applications.
