16-Output Switch with SPI 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, 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.
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.
