MC34SB0800AE

Power Management - Specialized Overview

The MC34SB0800AE is an octal valve and pump controller system on chip from NXP Semiconductors. It integrates four regulated low-side drivers and four digital low-side drivers, alongside two high-side drivers. The device supports a maximum voltage of 36V. Each low-side driver for solenoids delivers up to 2.25A with an on-resistance of 300mOhms. Operating at frequencies up to 5kHz, the component is housed in a 64-LQFP (10x10) package with an exposed pad.

Power Management - Specialized Feature Summary

• Integrates SMARTMOS technology for low RDSON and reduced power dissipation in load control switching.
• Provides comprehensive protection mechanisms including over current, over temperature, and over/under voltage safeguards.
• Combines regulated and digital low-side outputs with high-side drivers for versatile actuator control.

Power Management - Specialized Applications

• Automotive diesel engine management systems
• Valve driver circuits
• Pump controller applications

Power Management - Specialized Procurement Notes

Verify the specific suffix AE against official NXP documentation to confirm pinout and thermal characteristics. Ensure the 64-LQFP footprint matches the target PCB design. Cross-reference the datasheet revision date to validate feature availability and electrical limits before integration into production designs.

Power Management - Specialized Selection Notes

Select this component when designing automotive fuel or emission control systems requiring multiple independent solenoid channels. The integrated regulation and digital control options simplify circuit topology. Evaluate the 36V rating and 2.25A per channel capacity against peak load requirements to ensure adequate headroom for transient conditions.

Power Management - Specialized Part Context

This part belongs to NXP's specialized power management portfolio focused on engine control. It complements other devices like the MC34SB0410 by offering expanded channel counts. The series targets high-reliability automotive environments where precise valve timing and pump actuation are critical for performance and emissions compliance.

Power Management - Specialized Replacement Considerations

The MC34SB0410 is a related variant within the same family but offers fewer channels. Verify compatibility if substituting, as pinouts and driver configurations may differ. Consult official substitution guides to ensure functional equivalence without redesigning the host board.
