high level at this pin (within the data byte) will switch on the power switch, provided that the
corresponding parallel input is also switched on (AND-operation for channel 1 to 4).
SO
- Serial Output. Diagnostic data bits are shifted out serially at this pin, the most significant
bit first. SO is in a high impedance state until the
CS
pin goes to a logic low state. New diag-
nostic data will appear at the SO pin following the rising edge of SCLK.
RESET
- Reset pin. If the reset pin is in a logic low state, it clears the SPI shift register and
switches all outputs OFF. An internal pull-up structure is provided on chip.
Diagnostics
FAULT
- Fault pin. There is a general fault pin (open drain) which shows a high to low transi-
tion as soon as an error occurs for any one of the eight channels. This fault indication can be
used to generate a μC interrupt. Therefore a ‘diagnosis’ interrupt routine need only be called
after this fault indication. This saves processor time compared to a cyclic reading of the SO
information.
As soon as a fault occurs, the fault information is latched into the diagnosis register. A new
error will over-write the old error report. Serial data out pin (SO) is in a high impedance state
when
CS
is high. If
CS
receives a LOW signal, all diagnosis bits can be shifted out serially.
The rising edge of
CS
will reset all error registers.
There are two diagnostic bits per channel configured as shown in Figure 1.
Normal function:
The bit combination
HH
indicates that there is no fault condition, i.e. normal
function.
Overload, Short Circuit to Battery (SCB) or Overtemperature:
HL
is set when the current
limitation gets active, i.e. there is a overload, short to supply or overtemperature condition.
Open load:
An open load condition is detected when the drain voltage decreases below 3 V
(typ.).
LH
bit combination is set.
Short Circuit to GND:
If a drain to ground short circuit exists and the drain to ground current
exceeds 100 μA, short to ground is detected and the
LL
bit combination is set.
