Enable bit
If Enable Bit is set the
device will be switched in
active mode. If Enable Bit
is cleared device go into
standby mode and all bits
are cleared. After power-
on reset device starts in
standby mode.
Always 1
A broken VCC or SPI
connection of the L9950 can
be detected by the
microcontroller, because all 24
bits low or high is not a valid
frame.
22
Reset bit
If Reset Bit is set both
status registers will be
cleared after rising edge
of CSN input.
VS overvoltage
In case of an overvoltage or
undervoltage event the
corresponding bit is set and
the outputs are deactivated. If
VS voltage recovers to normal
operating conditions outputs
are reactivated automatically
(if Bit 20 of status register 0 is
not set).
21
OC recovery
duty cycle
This bit defines in
combination with the over-
current recovery bit (Input
Register 1) the duty cycle
in over-current condition
of an activated driver.
VS undervoltage
0: 12%
1:
25%
20
Overvoltage/Un
dervoltage
recovery disable
If this bit is set the
microcontroller has to
clear the status register
after
undervoltage/overvoltage
event to enable the
outputs.
Thermal
shutdown
In case of an thermal
shutdown all outputs are
switched off.
The microcontroller has to
clear the TSD bit by setting the
Reset Bit to reactivate the
outputs.
19
Depending on
combination of bit 18 and
19 the current image
(1/10.000) of the selected
HS output will be multi-
plexed to the CM output:
Temperature
warning
This bit is for information
purpose only. It can be used
for a thermal management by
the microcontroller to avoid a
thermal shutdown.

Output
Not ready bit
After switching the device from
standby mode to active mode
an internal timer is started to
allow charge pump to settle
before the outputs can be
activated. This bit is cleared
automatically after start up
time has finished. Since this
bit is controlled by internal
clock it can be used for
synchronizing testing events
(e.g. measuring filter times).

HS driver OUT6 is not
activated.
