The LMG1210is a 200-V, half-bridge MOSFET and Gallium Nitride Field Effect Transistor (GaN FET) driverdesigned for ultra-high frequency, high-efficiency applications that features adjustable deadtimecapability, very small propagation delay, and 3.4-ns high-side low-side matching to optimize systemefficiency. This part also features an internal LDO which ensures a gate-drive voltage of 5-Vregardless of supply voltage.

To enable best performance in a variety of applications, the LMG1210 allows the designerto choose the optimal bootstrap diode to charge the high-side bootstrap capacitor. An internalswitch turns the bootstrap diode off when the low side is off, effectively preventing the high-sidebootstrap from overcharging and minimizing the reverse recovery charge. Additional parasiticcapacitance across the GaN FET is minimized to less than 1 pF to reduce additional switchinglosses.

The LMG1210 features two control input modes: Independent Input Mode (IIM) and PWM mode.In IIM each of the outputs is independently controlled by a dedicated input. In PWM mode the twocomplementary output signals are generated from a single input and the user can adjust the deadtime from 0 to 20 ns for each edge. The LMG1210 operates over a wide temperature range from –40°Cto 125°C and is offered in a low-inductance WQFN package.
