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

Description: The LV5685PV is a multiple output linear regulator...
  • 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

  • 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.
