Preliminary Information
33999
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.

Notes
11. Output Fault Detect Thresholds with outputs programmed OFF. Output Fault Detect Thresholds are the same for output open and shorts.
12. Output OFF Open Load Detect Current is the current required to flow through the load for the purpose of detecting the existence of an open
load condition when the specific output is commanded to be OFF.
13. This parameter is guaranteed by design but is not production tested.

both input and output words transferring the Most Significant
Bit (MSB) first.
SO Output driver Power Supply (SOPWR) Pin
The SOPWR pin is used to supply power to the 33999 SO
output driver and Power-ON Reset (POR) circuit. To achieve
low standby current on VPWR supply, power must be removed
from the SOPWR pin. The 33999 will be in reset with all drivers
OFF when SOPWR is below 2.5 V. The 33999 does not detect
overvoltage on the SOPWR supply pin.
Output/Input (OUT0–OUT15) Pins
These pins are low-side output switches controlling the load.
Reset (RST) Pin
The Reset (RST) pin is the active low reset input pin used to
turn OFF all outputs, thereby clearing all internal registers.
Battery Input (VPWR) Pin
The VPWR pin is used as the input power source for the
33999. The voltage on VPWR is monitored for overvoltage
protection and shutdown. An overvoltage condition (> 50 µs)
on the VPWR pin causes the 33999 to shut down all outputs
until the overvoltage condition is removed. Upon return to
normal input voltage, the outputs respond as programmed by
the overvoltage bit in the Global Shutdown/Retry Control
register. The overvoltage threshold on the VPWR pin is
specified as 27.5 V to 35 V with 1.4 V typical hysteresis.
Following an overvoltage shutdown of output drivers, the
Overvoltage Fault and the Any Fault bits in the SO bit stream
will be logic [1].
PWM Pin
The PWM Control pin is provided to support PWM of any
combination of outputs. Logic for PWM control is provided in
the LOGIC OPERATION section (below).
Pulse Width Module (PWMn) Pins
PWM0, PWM1, PWM6, PWM7, PWM8, PWM9, PWM14,
and PWM15 input pins allow direct PWM control of OUT0,
OUT1, OUT6, OUT7, OUT8, OUT9, OUT14, and OUT15,
respectively. Logic for PWM control is provided in the LOGIC
OPERATION section.
LOGIC OPERATION
Introduction
The 33999 provides flexible control of 16 low-side driver
outputs. The device allows PWM and ON/OFF control through
the use of several input command words. This section
describes the logic operation and command registers of the
33999.
The 33999 message set consists of seven messages as
shown in Table 1. Bits 23 through 18 determine the specific
command and bits 15 through 0 determine how a specific
output will operate. The 33999 operates on the command word
on the rising edge of CS.
Note Upon Power-ON Reset all bits are defined as shown in
Table 1.
