MC33288DDH

Overview

The MC33288DDH is a power driver IC manufactured by NXP USA Inc., housed in a 20-HSOP package with exposed pad. It features two high-side outputs capable of delivering up to 8A per channel, operating within an 8V to 35V load voltage range. The typical on-resistance is 20 milliohms. Designed for surface mount installation, it supports open/switch interface control and functions across a junction temperature range of -40°C to 150°C. Key protection mechanisms include over-temperature shutdown and open load detection.
