Multi-Power Supply System IC
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.

For CD drive: 7.0V output voltage, 1300mA maximum output current
For illumination: 8 to 12V output voltage (output can be set with external resistors), 300mA maximum output current
For audio systems: 8 to 9V output voltage (output voltage can be set with external resistors), 300mA maximum
output current
• Two VCC-linked high side switch systems
EXT: 350mA maximum output current, 0.5V voltage difference between input and output.
ANT: 300mA maximum output current, 0.5V voltage difference between input and output.
• 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.

*1 : The VDD 5.7V output also supplies the output currents of SW 5.7V and ACC 5.7V. Therefore, the current supply capability of the VDD 5.7V output and its
other electrical characteristics are affected by the output statuses of SW 5.7V and ACC 5.7V.
*2 : SW 5V and ACC 5.7V are not subject to a load.
