Overview

The LV5680NPVC 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.

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

• 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

(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 or thermal shutdown state may degrade the IC’s reliability and eventually damage the IC.
