Multi-Power Supply IC
Overview
The LV56841PVD is a power supply IC suitable for CD receiver system for car audio system.
This IC integrates 5 systems of regulator output, 2 systems of high side power switch, over-current protector,
overvoltage protector and over-heat protector .
Supply for SW33V outputs is low voltage specification, which enables drastic reduction of power dissipation compared
to the existing model. (the package is HZIP15).
Function
• Low consumption current: 50μA (typ, only VDD output is in operation)
•5 systems of regulator output
VDD for microcontroller: output voltage: 3.3V, maximum output current: 350mA
Reverse current protection implemented.
For system: output voltage: 3.3V, maximum output current: 350mA
For audio: output voltage: 5 to 12V (set by external resistors), maximum output current: 300mA
For illumination: output voltage: 5 to 12V (set by external resistors), maximum output current: 300mA
For CD: output voltage: 6V, maximum output current: 1500mA
• 2 lines of high side switch with interlock VCC
EXT: Maximum output current: 500mA, voltage difference between input and output: 0.75V
ANT: Maximum output current: 300mA, voltage difference between input and output: 0.5V
• Supply input
V6IN: 6V for system (SW33V)
VCC1: For internal reference voltage, control circuits, and VDD output.
VCC2: For AUDIO, illumination, CD, EXT/ANT
• Over-current protector
• Overvoltage protector(OVP): VCC1,VCC2 Typ 21V (All outputs except VDD are turned off)
Overvoltage shutdown(OVS): V6IN Typ 21V (All outputs except VDD are turned off)
• Overheat protector: Typ 175°C
• Pch-LDMOS is used in power output block
(Warning) The protector functions only improve the IC’s tolerance and they do not guarantee the safety of the IC if used under the
conditions out of safety range or ratings. Use of the IC such as use under over-current protection range, thermal shutdown state or V6IN
OVS condition may degrade the IC’s reliability and eventually damage the IC.

*1 : All the specification is defined based on the tests performed under the conditions where Tj and Ta (= 25°C) are almost equal. These tests were performed
with pulse load to minimize the increase of junction temperature (Tj).
*2 : guaranteed by design
*3 : Using resistors of tolerance within 1%.
*4 : When the output current is over “Ilim5”, the over-current protector circuit operates. The over-current protector circuit is "fold-back" type, and it limits the
output current and voltage when it's operating. The output current should be usually limited below Iomax that is “min of Io5” .
Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product performance may not be
indicated by the Electrical Characteristics if operated under different conditions.

When CTRL pin transits between L and M2, since it passes M1, ILM is turned on for a moment. Likewise, when CTRL pin transits between H and M1, since it
passes M2, ILM is turned off for a moment.
To avoid operation failure by the above factors, please refer (1) and (2) as shown below for precaution.dd

HZIP15 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.
• 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 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.
