LV5686PVC
Bi-CMOS LSI
Multi-Power Supply IC
for Car Audio Systems
http://onsemi.com
Overview
LV5686PVC is a multiple voltage regulator for Car Audio System. This IC has 3 voltage regulators, 5V output for a
microcontroller, 9.85V output for illuminations, 9V output for audio control and 6 high side switches.
About protection circuits, it has Over-current-protection, Over-voltage-protection and Thermal-shut-down. This IC is
most suitable for Car Audio System.
Features
• 3 system regulators
VDD (MCU) : VOUT 5V, IOUT max 300mA, reverse current prevention.
Illumination : VOUT 9.85V, IOUT max 300mA
Audio
: VOUT 9.0V, IOUT max 500mA
• 6 high side switches
AMP : IOUT max 300mA, voltage difference between input and output: 1.0V
ANT : IOUT max 300mA, voltage difference between input and output: 1.0V
EXT1 : IOUT max 500mA, voltage difference between input and output: 1.0V
EXT2 : IOUT max 500mA, voltage difference between input and output: 1.0V
EXT3 : IOUT max 350mA, voltage difference between input and output: 0.5V
EXT4 : IOUT max 500mA, voltage difference between input and output: 1.0V
• Over Current Protection
• BATT. Detection: under voltage1 (<6.5V), under voltage2 (<9.5V) and over voltage (>18V)
• Over Voltage Protection Typ 25V (shutdown except VDD)
• Thermal Shut Down Circuit Typ 175°C
• Applied P-LDMOS to Output stage
(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, thermal shutdown
state or V6IN OVS condition may degrade the IC’s reliability and eventually damage the IC.
