Advance Information

16-Output Switch with SPI

and PWM Control

33999

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,

incandescent, and LED loads. The Serial Peripheral Interface (SPI)

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.

POWER DUAL OCTAL SERIAL SWITCH WITH

SERIAL PERIPHERAL INTERFACE I/O

The 33999 directly interfaces with microcontrollers and is

compatible with both 3.3 V and 5.0 V CMOS logic levels. The 33999,

in effect, serves as a bus expander and buffer with fault management

features that reduces the MCU’s fault management burden.
