LV5685PV: Linear Voltage Regulator, 5-Channel, 2 High-Side Switches

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.

Features

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 "SW33V" for system: output voltage: 3.3/5V(set by I2C-bus), maximum output current: 450mA "AUDIO" for audio: output voltage: 5/8.5/9/11.5V(set by I2C-bus), maximum output current: 250mA "ILM" for illumination: output voltage: 5/8/10.5/12V(set by I2C-bus), maximum output current: 300mA "CD" 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)
Low battery voltage detection(UVDET): detection voltage 6/7/7.8/9V(set by I2C-bus)
Battery 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 inputs - 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
