16 Output Switch with SPI
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. 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.
compatible with both 3.3 and 5.0V 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.
Features
• Designed to operate 5.0V < V
• 24 Bit SPI for control and fault reporting, 3.3/5.0V compatible
• Outputs are current limited (0.9 to 2.5A) to drive incandescent
• Output voltage clamp of +50V during inductive switching
• On/Off control of open load detect current (LED application)
• V
• R
• Independent over-temperature protection
• Output selectable for PWM control
• Output ON short-to-V
• Pb-free packaging designated by suffix code EK
The 33996 is a 16-output low side switch with a 24-bit serial input
The 33996 directly interfaces with micro controllers and is
