Description
The MPQ18914 is a high-frequency, half-bridge transformer driver. It is ideal for use as the primary-side MOSFET in isolated power supplies for biasing silicon carbide (SiC) field-effect transistors (FETs), silicon FETs, and insulated gate bipolar transistors (IGBTs). The MPQ18914 simplifies isolated biased supply design by integrating the control, switching power stage, and protection circuitry into a single device. This topology supports designs with a high isolation voltage and small interwinding capacitance.
The MPQ18914 features soft switching to optimize EMI performance. It supports a wide 5V to 30V input voltage (VIN) range, and can survive surges of up to 50V. The device has a wide 400kHz to 3MHz configurable switching frequency (fSW) range, which reduces solution size and optimizes efficiency in resonant topologies (e.g. LLC converters).
Full safety and protection features include input over-voltage protection (OVP), over-current protection (OCP), and fault indication. The device’s built-in soft start (SS) controls the inrush current during start-up.
The MPQ18914 is available in a QFN-10 (2mmx2.5mm) package with wettable flanks, and is available in AEC-Q100 Grade 1.

APPLICATION
TRACTION INVERTER SYSTEMAPPLICATIONAn engine roaring is becoming a sound of the past, as the adoption of electric vehicles (EVs) continues to grow at an exponential rate. Soon the only sound will be the whirring an EV motor as the traction inverter delivers power from the battery. Traction inverters are instrumental in converting energy from the high-voltage battery (400V/800V) into three-phase AC energy to drive the vehicle’s moto...

APPLICATION
ONBOARD CHARGING MODULE (OBCM)APPLICATIONElectric vehicles (EVs) are becoming more present every day, with the adoption of EVs growing at an exponential rate. Onboard charging (OBC) is a very important part of EVs, since it determines the maximum possible charge rate while an AC charger is connected to the vehicle. The maximum charge capability for a fully electric vehicle is typically between 6.6kW and 22kW, and for a plug-in hybrid veh...
