MC33298DW Description

Short technical summary and product information.

The MC33298DW from NXP Semiconductors is a versatile, eight-output low-side power switch designed for controlling moderate current loads such as solenoids, relays, lamps, and small DC motors. It features an 8-bit serial-in shift register controlling an 8-bit parallel output latch, enabling independent ON/OFF control for each of the eight outputs.

 

This device interfaces directly with microcontrollers via an 8-bit SPI I/O protocol, supporting data rates up to 3.0 MHz. It operates over a wide supply voltage range of 5.5V to 26.5V. Each output utilizes high-efficiency MOSFET power transistors with open drains, capable of sinking up to 3.0A of transient current. Continuous current handling per output is 0.5A when the device is soldered onto a typical PC board, with higher currents dependent on the number of simultaneously active outputs.

 

Innovative monitoring and protection features include current limiting, open load detection, over-temperature, and over-voltage protection. The device also offers a very low standby current of 25µA. The MC33298DW is available in a 24-SOIC surface-mount package, suitable for various industrial and automotive applications requiring robust power switching capabilities.
