Preliminary Information
16-Output Switch with SPI Control
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 microcontrollers 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.
