Rev. 8.0, 8/2008

Freescale Semiconductor

Advance Information

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.

LOW SIDE SWITCH

The 33996 directly interfaces with micro controllers and is

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_PWR< 27V

• 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

lamps

EK SUFFIX (PB-FREE)

32-PIN SOICW EXPOSED PAD

• Output voltage clamp of +50V during inductive switching

• On/Off control of open load detect current (LED application)

• V_PWRstandby current < 10μA

• R_DS(ON)of 0.55Ω at 25°C typical

• Independent over-temperature protection

• Output selectable for PWM control
