Overview
The LV5681P is a multi-power supply system IC that provides four regulator outputs and two high side switches as
well as a number of protection functions including overcurrent protection, overvoltage protection and overheat
protection. It is an optimal power supply IC for car audio and car entertainment systems and similar products.

• Two VDD 5V-linked high side switch systems
SW5V: 200mA maximum output current, 0.2V voltage difference between input and output.
ACC (accessory voltage detection output): 100mA maximum output current, 0.2V voltage difference between
input and output.
• Overcurrent protection function
• Overvoltage protection function, typ 21V (excluding VDD 5V output)
• Overheat protection function, typ 175ºC
• On-chip accessory voltage detection circuit
• P-channel LDMOS used for power output block
CAUTION)
The protection functions are provided in order to improve the ability of the ICs to withstand breakdown, and they are not intended to guarantee
safety when used under conditions outside the safe operating area or rated operating conditions.
Use of the ICs under any conditions exceeding the safe operating area or above the IOmax, and especially use in overcurrent protection areas or under
conditions in which they are subject to thermal protection, may reduce their reliability and result in permanent breakdown.

Caution for implementing LV5681P to a system board
In HZIP15J, the package used in this IC, there are several metal exposure other than the connection pins and heat-sinks as shown in
the following diagrams. In the diagrams, the electric potential of 2 and 3 are the same as Pin15 and Pin1, respectively. 2 (=Pin15) is
EXT pin and 3 (=Pin1) is ILM output (regulator). When the IC is implemented to the system, make sure that no attachment clamp
touches the exposed Pin1/ Pin15. When the exposed Pin1/ Pin15 touch the attachment clamp (same electrical potential as GND), ILM
output or VCC enter the same state as time when GND was shorted. The electric potential of the exposed metal connected to heat-sinks
1 is the same as that of sub board of the IC (GND). Therefore, even if the exposed metal and GND of the system board are adjacent to
each other, there should be no problem.

HZIP15J Heat sink attachment
Heat sinks are used to lower the semiconductor device junction temperature by leading the head generated by the device to
the outer environment and dissipating that heat.
a. Unless otherwise specified, for power ICs with tabs and power ICs with attached heat sinks, solder must not be
applied to the heat sink or tabs.
b.
Heat sink attachment
· Use flat-head screws to attach heat sinks.
· Use also washer to protect the package.
· Use tightening torques in the ranges 39-59Ncm(4-6kgcm) .
· If tapping screws are used, do not use screws with a diameter larger
than the holes in the semiconductor device itself.
· Do not make gap, dust, or other contaminants to get between the
semiconductor device and the tab or heat sink.
· Take care a position of via hole .
· Do not allow dirt, dust, or other contaminants to get between the
semiconductor device and the tab or heat sink.
· Verify that there are no press burrs or screw-hole burrs on the heat sink.
· Warping in heat sinks and printed circuit boards must be no more than
0.05 mm between screw holes, for either concave or convex warping.
· Twisting must be limited to under 0.05 mm.
· Heat sink and semiconductor device are mounted in parallel.
Take care of electric or compressed air drivers
· The speed of these torque wrenches should never exceed 700 rpm, and
should typically be about 400 rpm.

c.
Silicone grease
· Spread the silicone grease evenly when mounting heat sinks.
· Our company recommends YG-6260 (Momentive Performance Materials Japan LLC)
d.
Mount
· First mount the heat sink on the semiconductor device, and then mount that assembly on the printed circuit board.
· When attaching a heat sink after mounting a semiconductor device into the printed circuit board, when tightening
up a heat sink with the screw, the mechanical stress which is impossible to the semiconductor device and the pin
doesn't hang.
e.
When mounting the semiconductor device to the heat sink using jigs, etc.,
· Take care not to allow the device to ride onto the jig or positioning dowel.
· Design the jig so that no unreasonable mechanical stress is not applied to the semiconductor device.
f.
Heat sink screw holes
· Be sure that chamfering and shear drop of heat sinks must not be larger than the diameter of screw head used.
· When using nuts, do not make the heat sink hole diameters larger than the diameter of the head of the screws used.
A hole diameter about 15% larger than the diameter of the screw is desirable.
· When tap screws are used, be sure that the diameter of the holes in the heat sink are not too small. A diameter about
15% smaller than the diameter of the screw is desirable.
g.
There is a method to mount the semiconductor device to the heat sink by using a spring band. But this method is not
recommended because of possible displacement due to fluctuation of the spring force with time or vibration.
