16-Output Switch with SPI
and PWM Control
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.
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.
Features
