16-Output Switch with SPI Control

MC33996 Active

The NXP® MC33996 is a 16-output low-side switch with a 24-bit serial input control, designed for a variety of applications including inductive, incandescent, and LED loads.

  • The SPI provides both input control and diagnostic readout
  • A Pulse-Width Modulation (PWM) control input may be used to pulse width modulate multiple outputs at the same duty cycle
  • A dedicated reset input provides the ability to clear all internal registers to the Power-ON Reset state.
  • Directly interfaces with MCUs and is compatible with both 3.3 V and 5.0 V CMOS logic levels
