MPQ18811-AEC1 Series Isolated, Single-Channel Gate Drivers

Monolithic Power Systems isolated, single-channel gate drivers are AEC-Q100 qualified

Image of Monolithic Power Systems MPQ18811-AEC1The MPQ18811 from Monolithic Power Systems is an isolated, single-channel gate driver solution with up to 6 A of source and up to 10 A of sink peak current capacity. The gate driver is designed to drive power switching devices with short propagation delay and pulse-width distortion.

By utilizing capacitive-based isolation technology, the driver can provide 5 kVRMS of withstand voltage (per UL 1577) with an SOIC wide-body (WB) package and above 150 kV/μs of common-mode transient immunity (CMTI) rating between the input side and the output driver. With these advanced features, the driver operates at high efficiency, high power density, and with robustness in a wide variety of automotive power applications.

A wide 2.8 V to 5.5 V primary-side input power supply (VDDI) range allows the driver to be interfaced with 3.3 V or 5 V digital controllers. The secondary-side driver accepts up to a 30 V supply. All the supply pins feature various under voltage lockout (UVLO) protection levels.

The MPQ18811 is available in SOIC-8 narrow-body (NB) or wide-body (WB) packages.
