The LMG1205 is designed to drive both
the high-side and the low-side enhancement mode Gallium Nitride (GaN) FETs in a
synchronous buck, boost, or half-bridge configuration. The device has an integrated
100-V bootstrap diode and independent inputs for the high-side and low-side outputs
for maximum control flexibility. The high-side bias voltage is generated using a
bootstrap technique and is internally clamped at 5 V, which prevents the gate
voltage from exceeding the maximum gate-source voltage rating of enhancement mode
GaN FETs. The inputs of the LMG1205 are TTL logic compatible and can withstand input
voltages up to 14 V regardless of the VDD voltage. The LMG1205 has split-gate
outputs, providing flexibility to adjust the turnon and turnoff strength
independently.
In addition, the strong sink
capability of the LMG1205 maintains the gate in the low state, preventing unintended
turnon during switching. The LMG1205 can operate up to several MHz. The LMG1205 is
available in a 12-pin DSBGA package that offers a compact footprint and minimized
package inductance.
