Overview
The LV5684PVD is a power supply IC suitable for USB/CD receiver system for car audio system.
This IC integrates 5 systems of regulator output, 2 systems of high side power switch, overcurrent protector,
overvoltage protector and overheat protector
Supply for VDD and 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)
• 5 systems of regulator output
VDD for microcontroller: output voltage: 3.3V, maximum output current: 350mA reverse current protection
implemented.
For system: output voltage: 3.3V, maximum output current: 450mA
For audio: output voltage: 5 to 9V (set by external resistors), maximum output current: 250mA
For illumination: output voltage: 5 to 12V (set by external resistors), maximum output current: 300mA
For CD: output voltage: 5V/8V, maximum output current: 1300mA
• 2 lines of high side switch with interlock VCC
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
• Supply input
V6IN: 6V for VDD, system (SW33V)
VCC1: For internal reference voltage, control circuits
In case of voltage drop of V6IN, VCC1 supplies to VDD output.
VCC2: For AUDIO, illumination, CD, EXT/ANT
• Overcurrent protector
• Overvoltage protector(OVP): VCC1,VCC2 Typ 23V (All outputs except VDD are turned off)
Overvoltage shutdown(OVS): V6IN Typ 23V (All outputs except VDD are turned off)
• Overheat protector: Typ 175°C
• PchLDMOS is used in power output block
(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.
