MCZ33810EK

The MCZ33810EK from NXP Semiconductors is a specialized integrated circuit designed for automotive engine control systems. This device features eight output channels, comprising four integrated low-side drivers and four low-side gate pre-drivers. The low-side drivers are versatile, capable of driving fuel injectors, solenoids, lamps, and relays. The gate pre-drivers can be configured as ignition IGBT gate pre-drivers or general-purpose MOSFET gate pre-drivers, offering flexibility in design.

This IC is powered by SMARTMOS technology and supports direct interfacing with MCUs via SPI protocol (3.3 V / 5.0 V). It is designed to operate within a wide power supply range of 4.5 V to 36 V and functions across an operating temperature range of -40°C to 125°C. Key features include an injector driver current limit of up to 4.5 A and independent fault protection and diagnostics.

The MCZ33810EK is packaged in a 32-pin SOIC with an exposed pad (32-SOIC-EP) and supports surface mount technology. Its applications extend to automotive, motorcycle engine control units (ECUs), small engine control, PSI5 airbag systems, central gateway/in-vehicle networking, braking and stability control, gasoline engine management, and hybrid electric vehicle (HEV) inverter controllers.
