LV56841PVD: 5-Channel Linear Voltage Regulator with 2 High-Side Switches for Automotive Infotainment

The LV56841PVD is a power supply IC suitable for CD receiver system for car audio system. This IC integrates 5 linear voltage regulators, 2 systems of high side power switch, over-current protector, overvoltage protector and over-heat protector . Supply for SW33V outputs is low voltage specification, which enables drastic reduction of power dissipation compared to the existing model. (the package is HZIP15).

Features
  • Low consumption current: 50µA (typ, only VDD output is in operation)
  • Regulator output 1 - VDD for microcontroller: output voltage: 3.3V, maximum output current: 350mAReverse current protection implemented.
  • Regulator output 2 - For system: output voltage: 3.3V, maximum output current: 350mA
  • Regulator output 3 - For audio: output voltage: 5 to 12V (set by external resistors), maximum output current: 300mA
  • Regulator output 4 - For illumination: output voltage: 5 to 12V (set by external resistors), maximum output current: 300mA
  • Regulator output 5 - For CD: output voltage: 6V, maximum output current: 1500mA
  • high side switch with interlock VCC 1 - EXT: Maximum output current: 500mA, voltage difference between input and output: 0.75V
  • high side switch with interlock VCC 2 - ANT: Maximum output current: 300mA, voltage difference between input and output: 0.5V
  • V6IN: 6V for system (SW33V)
  • VCC1: For internal reference voltage, control circuits, and VDD output.
  • VCC2: For AUDIO, illumination, CD, EXT/ANT
  • Over-current protector
