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.
PWM FREQUENCY/DUTY CYCLE COMMAND
The PWM Frequency/Duty Cycle Command allows the
Table 10. VDSNSx Fault Threshold Select
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
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.

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
