LV5685PV
Bi-CMOS LSI
System Power Supply IC
for Automotive Infotainment
Multiple-Output Linear Voltage Regulator
http://onsemi.com
Overview
The LV5685PV is a multiple output linear regulator IC, which allows reduction of quiescent current. The LV5685PV is
specifically designed to address automotive infotainment systems power supply requirements.
The LV5685PV integrates 5 linear regulator outputs, 2 high side power switches, I2C-bus communication, ACC
detection, battery voltage detection, over-current limiter, overvoltage protection and thermal shut down. Supply for
VDD and SW33V outputs is low voltage specification, which enables drastic reduction of power dissipation compared
to the existing model.
Function
• Low consumption current: 65μA (typ, only VDD output is in operation)
• 5 regulator outputs
VDD for microcontroller: output voltage: 3.3V, maximum output current: 350mA
For system: output voltage: 3.3/5V(set by I2C-bus), maximum output current: 450mA
For audio: output voltage: 5/8.5/9/11.5V(set by I2C-bus), maximum output current: 250mA
For illumination: output voltage: 5/8/10.5/12V(set by I2C-bus), maximum output current: 300mA
For CD: output voltage: 5/6/7/8V(set by I2C-bus), maximum output current: 1300mA
• 2 high side switches
EXT: Maximum output current: 350mA, voltage difference between input and output: 0.5V
ANT: Maximum output current: 300mA, voltage difference between input and output: 0.5V
• ACC detection circuit
detection voltage 2.7/3.2/3.6/4.2V (set by I2C-bus)
• Battery voltage detection (BDET) : VCC2
Low voltage detection(UVDET): detection voltage 6/7/7.8/9V(set by I2C-bus)
Over voltage detection(OVDET): detection voltage 18V
• FLG output
CMOS output of ACC-detection/UVDET/OVDET/OVP
• I2C-bus communication interface
Each output except VDD is independently enabled/disabled. ILM/CD/AUDIO/ACC/UV voltage setting.
Read back supported: Output voltage setting, Output over-current, FLG(ACC/UV/OVDET/OVP)
• Supply input
V6IN: 6V for VDD, system(SW33V)
VCC1: For internal reference voltage, control circuitry
In case of voltage drop of V6IN, VCC1 supplies VDD output.
VCC2: For AUDIO/ILM/CD/EXT/ANT
• Over-current protection
• Overvoltage protection(OVP):
VCC1, VCC2 Typ 23V (All outputs except VDD are turned off)
• Thermal shutdown: Typ 175°C
