Freescale Semiconductor Advance Information 16 Output Switch with SPI Control The 33996 is a 16-output low side switch with a 24-bit serial input control. It is designed for a variety of applications including inductive, incandescent, and LED loads. The Serial Peripheral Interface (SPI) provides both input control and diagnostic readout. A Pulse Width Modulation (PWM) control input is provided for pulse width modulation of multiple outputs at the same duty cycle. A dedicated reset input provides the ability to clear all internal registers and turn all outputs off. The 33996 directly interfaces with micro controllers and is compatible with both 3.3 and 5.0V CMOS logic levels.
