Document Number: MC33999 Freescale Semiconductor Rev. 6.0, 2/2014 Technical Data 16-Output Switch with SPI 33999 and PWM Control The 33999 is a 16-output low-side switch with a 24-bit serial input control. It is designed for a variety of applications including inductive, POWER DUAL OCTAL SERIAL SWITCH WITH incandescent, and LED loads. The Serial Peripheral Interface (SPI) SERIAL PERIPHERAL INTERFACE I/O provides both input control and diagnostic readout. Eight parallel inputs are also provided for direct Pulse Width Modulation (PWM) control of eight dedicated outputs. Additionally, an output-programmable PWM input provides PWM of any combination of outputs. A dedicated reset input provides the ability to clear all internal registers and turn all outputs off. The 33999 directly interfaces with microcontrollers and is compatible with both 3.3 V and 5.0 V CMOS logic levels. The 33999, EK SUFFIX (PB-FREE) in effect, serves as a bus expander and buffer with fault management 98ASA10506D features that reduces the MCUs fault management burden. This 54-PIN SOICW EXPOSED PAD device is powered by SMARTMOS technology.
