PWM FREQUENCY/DUTY CYCLE COMMAND
The PWM Frequency/Duty Cycle Command allows the
user to individually program a PWM output with a frequency
and duty cycle. Once the PWM Freq/DC registers are
programmed, the PWM output GD1, GD2, GD3 are
controlled via the AND/OR command and GD4, GD5, GD6
are controlled via the PWM pin Enable Command. Pre-driver
output control bits supersede the internal PWM controller.
GDx outputs must be commanded OFF for the controller to
function. (See
Table 8
)
The duty cycle of the PWM outputs is controlled by bits 0
through 6, inclusive. The duty cycle value is 1% per binary
count from 1 to 100 with counts of 101 through 127 defaulting
to 100%. For example:
Sending SPI WORD; 01100x1110001100
This would set PWM1 output to 1.28Khz frequency with a
12% duty cycle.
Table 9
defines the output frequency with the selected
input bits.

VDSNSX SHORT THRESHOLD COMMAND
The short fault threshold voltage of the external MOSFET
may be programmed via SPI.
Table 10
illustrates the bit
pattern required for a particular short fault threshold. Open
load fault detect threshold is set internally to 2.5V and may
not be programmed.
VDSNSX SHORT FAULT TIMER COMMAND
The Short Fault Timer can be programmed via the SPI to
the values listed in
Table 11, on page 24
. When the 33800
detects an over-current condition, as defined by V
DS
exceeding the programmed short fault voltage threshold, the
