FUNCTIONAL DEVICE OPERATION
PROTECTION AND DIAGNOSTIC FEATURES
OVERCURRENT FAULT (LATCHING)
The 33580 has eight programmable overcurrent low
detection levels (I OCL ) and two programmable overcurrent
high detection levels (I OCH ) for maximum device protection.
The two selectable, simultaneously active overcurrent
detection levels, defined by I OCH and I OCL , are illustrated in
If the load current level ever reaches the selected
overcurrent low detection level and the overcurrent condition
exceeds the programmed overcurrent time period (t OC x ), the
device will latch the output OFF.
If at any time the current reaches the selected I OCH level,
then the device will immediately latch the fault and turn OFF
the output, regardless of the selected t och driver.
For both cases, the device output will stay off indefinitely
until the device is commanded OFF and then ON again.
OVERVOLTAGE FAULT (NON-LATCHING)
The 33580 shuts down the output during an overvoltage
fault (OVF) condition on the V PWR pin. The output remains in
the OFF state until the overvoltage condition is removed.
When experiencing this fault, the OVF fault bit is set in the bit
D1 and cleared after either a valid SPI read or a power reset
of the device.
The overvoltage protection can be disabled through SPI
UNDERVOLTAGE SHUTDOWN (LATCHING OR
NON-LATCHING)
The output(s) will latch off at some battery voltage below
6.0 V. As long as the V DD level stays within the normal
specified range, the internal logic states within the device will
be sustained.
In the case where battery voltage drops below the
undervoltage threshold (VPWRUV) output will turn off, FS will
go to logic 0, and the fault register UVF bit will be set to 1.
Two cases need to be considered when the battery level
recovers :
? If outputs command are low, FS will go to logic 1 but the
UVF bit will remain set to 1 until the next read operation
(warning report).
? If the output command is ON, then FS will remain at
logic 0. The output must be turned OFF and ON again
to re-enable the state of output and release FS. The
UVF bit will remain set to 1 until the next read operation.
The undervoltage protection can be disabled through SPI
(bit UV_dis = 1). In this case, the FS does not report any
undervoltage fault condition, UVF bit is set to 1, and the
output state is not changed as long as the battery voltage
does not drop any lower than 2.5 V.
In case of V PWR is missing, the daisy chain feature is
available under V DD in nominal conditions.
(bit OV_DIS). When disabled, the returned SO bit OD13 still
reflects any overvoltage condition (overvoltage warning).
