MPQ18914

30V, High-Frequency Transformer Driver for Automotive Applications, AEC-Q100 Qualified

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 in a single device. This topology supports designs with a high isolation voltage and small interwinding capacitance. The low parasitic capacitance enables a significant reduction of the common-mode current flowing through the transformer.

The MPQ18914 features soft switching to optimize EMI performance. It supports a wide 5V to 30V input voltage (V_IN) range, and can survive surges of up to 50V.

The MPQ18914 has a wide 400kHz to 3MHz configurable switching frequency (f_SW) range, which reduces the 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 AEC-Q100 qualified.
