MC33879TEKR2

Full Half-Bridge (H Bridge) Drivers Overview

The MC33879TEKR2 is an octal power switch driver manufactured by NXP USA Inc., housed in a 32-SOIC-EP package. It features eight hardware-configurable high-side or low-side outputs, each capable of delivering up to 600mA with a typical on-resistance of 750 milliohms. The device operates with a load voltage range of 5.5V to 27.5V and a supply voltage of 3.1V to 5.5V. Control is managed via a 16-bit SPI interface. Integrated fault protections include fixed current limiting, open-load detection, and overvoltage protection. It supports PWM applications for two outputs and functions within a temperature range of -40°C to 125°C.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify component authenticity through authorized distributors as the part status is obsolete. Confirm package integrity and pin alignment against the 32-SOIC-EP specification. Ensure compatibility with existing SPI communication protocols and voltage levels before integration. Review available replacement options due to end-of-life status.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when eight independently controllable switches are required with high-side or low-side flexibility. The 600mA per channel rating suits moderate current loads like lamps and small motors. SPI interface simplifies microcontroller integration compared to parallel control schemes. Consider thermal management requirements given the surface mount packaging and operating temperature range.
