8.0, 4/2007 Quad High-Side Switch (Quad 35 mΩ) The 33874 is one in a family of devices designed for low-voltage automotive and industrial lighting and motor control applications.

Its four low RDS(ON) MOSFETs (four 35 mΩ) can control the high sides of four separate resistive or inductive loads.

Programming, control, and diagnostics are accomplished using a 16-bit SPI interface.

Additionally, each output has its own paral
