MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA
33880

Output Voltage Clamp
Each output of the 33880 incorporates an internal voltage
clamp to provide fast turn-off and transient protection of each
output. Each clamp independently limits the drain-to-source
voltage to 45 V for low-side drive configurations and -20 V for
high-side drive configurations (see
Figure 22
). The total energy
clamped (E
J
) can be calculated by multiplying the current area
under the current curve (I
A
) times the clamp voltage (V
CL
).
Characterization of the output clamps, using a single pulse
non-repetitive method at 0.3 A, indicates the maximum energy
to be 50 mJ at 150
°
C junction temperature per output.

SPI Configurations
The SPI configuration on the 33880 device is consistent with
other devices in the OSS family. This device may be used in
serial SPI or parallel SPI with the 33291 and 33298. Different
SPI configurations may be provided. For more information,
contact Analog Products Division.
Reverse Battery
The 33880 has been designed with reverse battery
protection on the V
PWR
pin. However, the device does not
protect the load from reverse battery. During the reverse battery
condition, current will flow through the load via the output
MOSFET substrate diode. Under this circumstance relays may
energize and lamps will turn on. If load reverse battery
protection is desired, a diode must be placed in series with the
load.
