Monolithic Power Systems (MPS) MPQ1918 Half-Bridge GaN/MOSFET Drivers

Monolithic Power Systems (MPS) MPQ1918 Half-Bridge GaN/MOSFET Drivers are designed to drive enhancement mode Gallium Nitride (GaN) FETs or N-channel MOSFETs with a low gate threshold voltage. These half-bridge drivers feature independent High-Side (HS) and Low-Side (LS) Pulse-Width Modulation (PWM) inputs. The MPQ1918 half-bridge drivers provide a bootstrap technique for the HS driver voltage to operate up to 100VDC. These drivers include a 3.7V to 5.5V (VCC) voltage range, 0.27Ω/1.2Ω pull-down/pull-up resistance, and separate gate outputs for adjustable turn-On and turn-Off capabilities. The MPQ1918 half-bridge drivers are AEC-Q100 Grade 1 qualified and available in an FCQFN-14 package. Typical applications include Half-bridge and full-bridge converters, audio class-D amplifiers, synchronous buck converters, and power modules.
