Overview
The LV56841PVD is a power supply IC suitable for CD receiver system for car audio system.
This IC integrates 5 systems of regulator output, 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).
Function
• 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: 350mA
For audio: output voltage: 5 to 12V (set by external resistors), maximum output current: 300mA
For illumination: output voltage: 5 to 12V (set by external resistors), maximum output current: 300mA
For CD: output voltage: 6V, maximum output current: 1500mA
• 2 lines of high side switch with interlock VCC
EXT: Maximum output current: 500mA, voltage difference between input and output: 0.75V
ANT: Maximum output current: 300mA, voltage difference between input and output: 0.5V
• Supply input
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
• Overvoltage protector(OVP): VCC1,VCC2 Typ 21V (All outputs except VDD are turned off)
Overvoltage shutdown(OVS): V6IN Typ 21V (All outputs except VDD are turned off)
• Overheat protector: Typ 175°C
• Pch-LDMOS 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 over-current protection range, thermal shutdown state or V6IN
OVS condition may degrade the IC’s reliability and eventually damage the IC.
