Analog, Mixed Signal and Power Management MC15XS3400 Quad 15 mOhm High Side Switch Overview to drive high-intensity discharge (HID) light W/28 W bulbs, and/or Xenon modules, and/or Freescale Semiconductor’s third generation of sources, improve efficiency, reduce wire LEDs. Programming, control, and diagnostics its award-winning eXtreme Switch portfolio harness size, and provide increased protection are accomplished using a 16-bit SPI interface. features devices tailored for automotive lighting for longer bulb life. Featuring four low Its output with selectable slew rate improves applications. These high side power switches RDS(ON) MOSFETs (quad 15 mΩ), the electromagnetic compatibility (EMC) behavior. include the MC15XS3400, which is designed MC15XS3400 can control four separate 55 Additionally, each output has its own parallel input or SPI control for pulse-width modulation (PWM), control if desired.
