Pin Functions
Pin No.
Symbol
Description
Remarks
Equivalent Circuit
1
9V Limitter
Used with an external CMOS regulator
to make up a backup power supply.
Blocks current from flowing into the IC
when VCC is turned off.
2
Swutched REF
Transistor switch that conducts current
when Power CONT is set high.
For controlling external
transistors.
3
Power CONT
7.5V regulator and Switched REF
output control (high active)
On/off control of this pin is enabled
when predefined voltage is
present at the VCC and REF 5V
pins.
4
REF 5V
Power source for the on/off and remote
controller STBY circuits
Supplied from the backup power
supply
5
PWR DET IN
Input pin for detecting the source
voltage
The threshold level is determined by
external resistors.
VCC (DET) = Vref (1+
)
Vref ≈ 1.2V
6
PWR DET
Supply voltage detection output
7
AC STBY
AC power monitoring input
8
MUTE OUT
Independent transistor switch (output)
9
MUTE IN
Independent transistor switch (input)
Used for mute operation, etc.
10
GND
Lowest voltage level of this IC
11
Remocon STBY
Used to control the remote controller
power supply via the Power DET and
AC STBY pins.
Stops function of the remote
controller when voltage drops.
12
VCC
External power supply input pin
13
7.5V
7.5V low saturation regulator output
On/off of this pin is controlled by Power
CONT.
