16-Output Switch with SPI
Control
33996
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 V and 5.0 V CMOS logic levels. The 33996,
in effect, serves as a bus expander and buffer with fault management
features that reduce the MCU’s fault management burden.
