MC33186DH2

Full Half-Bridge (H Bridge) Drivers Overview

The MC33186DH2 is a high-performance H-bridge gate driver manufactured by NXP Semiconductors, designed for driving brushed DC motors and other high-current loads. It integrates two independent output channels capable of handling up to 6A continuous current with a maximum voltage rating of 40V per FET. The device features a low on-resistance (RDS(on)) of 150 mΩ to minimize power loss and heat generation. It operates within an extended temperature range from -40°C to +125°C and utilizes an HSOP-20 surface-mount package. Key electrical parameters include a minimum supply voltage of 5V and a maximum standby current of 20mA.
