band and below 8.0MHz so that harmonics do not get within the FM radio band.
Waveshaping
Both the turn on and the turn off slew rates on all outputs (OUTPUT1-8) are limited to reduce conducted EMC
energy in the vehicle's wiring harness.
The characteristic of the turn-on and turn-off voltage is linear, with no discontinuities, during the output driver
state transition.
POR Register Initialization
L9848 wakes up if the VDD supply increases from 0 to 5VDC in 0.3ms to 3ms.
The L9848 has a POR circuit, which monitors the VDD voltage. When the VDD voltage reaches roughly
4.1VDC, and remains above this trip level for minimum 20μs, the Command and Fault Registers are "cleared".
Before VDD reaches this trip level, all eight outputs are guaranteed in OFF-state.
After a valid POR has occurred and the VDD voltage falls below the valid high level for a required amount of
time, the L9848 is powered down in a fully controlled manner. No outputs will glitch "ON" and no erroneous fault
data is allowed on the DO output.
Abnormal Voltage Conditions
The L9848 survives the following abnormal voltage conditions.
–
Reverse Battery
applied either directly, or through a load to the drain pins (DRN1-6) with the source pins (SRC1-6)
connected to a load or to ground (cold lamp, solenoid, etc).
–
Maximum Negative Transients
that force the drains or sources of the outputs going -20V below the module ground.
–
Ground Offsets
with a maximum of -0.5V to 1.0V between the L9848 ground and any load directly connected to a
chassis ground in the case of high side loads. If driving a low side load there will not be an offset be-
tween the L9848 ground and the load ground. In addition there may be a maximum ground difference
between the L9848 ground and any other module interfacing with it of -0.5V to 1.0V or ±VAC (10-
200Hz).
–
Loss of Ground Operation
Any outputs are protected to become active in case of lost ground of the L9848 module with the sup-
ply is still applied.
