LV5682P
Bi-CMOS LSI
Multi-Power Supply System IC
for Car Audio Systems
http://onsemi.com
Overview
The LV5682P 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 and overheat protection. It is an optimal power supply
IC for car audio and car entertainment systems and similar products. It is possible to use it like the bus track etc. in the
vehicle whose voltage of the battery is 24V because there is a range of the power-supply voltage up to 32V.
Features
Four regulator output systems
For microcontroller: 5.0V output voltage, 200mA maximum output current
For CD drive: 8.0V 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
Overheat protection function, typ 175ºC
On-chip accessory voltage detection circuit
P-channel LDMOS used for 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 overcurrent protection range or thermal shutdown state may
degrade the IC’s reliability and eventually damage the IC.
