MCZ33810EKR2

The MCZ33810EKR2 from NXP Semiconductors is an eight-channel output driver integrated circuit specifically designed for automotive engine control applications. This device utilizes SMARTMOS technology and comprises four integrated low-side drivers and four low-side gate pre-drivers.

The low-side drivers are suitable for various automotive loads such as fuel injectors, solenoids, lamps, and relays. The four gate pre-drivers can be configured as ignition IGBT gate pre-drivers or as general-purpose MOSFET gate pre-drivers. When used for ignition control, features like spark duration, dwell time, and ignition coil current sense are enabled. As a general-purpose gate pre-driver, it offers short-circuit protection, inductive flyback protection, and diagnostics for external MOSFETs.

This IC is designed to operate over a wide power supply voltage range of 4.5 V to 36 V. It interfaces directly with microcontrollers using a 3.3 V / 5.0 V SPI protocol. The injector driver has a maximum current limit of 4.5 A, and the device provides independent fault protection and diagnostics. The MCZ33810EKR2 features a low standby current of 10 µA maximum.

Packaged in a 32-pin SOIC with an exposed pad (32-SOIC-EP), this component is designed for surface mount applications. Its operating temperature range is -40°C to 125°C, making it suitable for demanding automotive environments. Applications include motorcycle engine control units, 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.
