FUNCTIONAL DESCRIPTION
The TDA3609JR is a multiple output voltage regulator with
a power switch, intended for use in car radios with or
without a microcontroller. Because of low-voltage
operation of the car radio, low-voltage drop regulators are
used in the TDA3609JR.
Regulator 2 will switch on when the back-up voltage
exceeds 6.5 V for the first time and will switch off again
when the output voltage of regulator 2 is below 1.9 V (this
is far below an engine start). When regulator 2 is switched
on and the output voltage of this regulator is within its
voltage range, the reset output will be enabled (reset will
go HIGH via a pull-up resistor) to generate a reset to the
microcontroller. The reset cycles can be extended by a
external capacitor at pin 13. The above mentioned start-up
feature is built-in to secure a smooth start-up of the
microcontroller at first connection, without uncontrolled
switching of regulator 2 during the start-up sequence.
The charge of the back-up capacitor can be used to supply
regulator 2 for a short period when the supply falls down
to 0 V (time depends on value of storage capacitor).
The output stages (regulator 1 and 3) of this regulator have
extreme low noise behaviour and good stability. Using
small output capacitors regulator 1 and 3 are made stable.
When both regulator 2 and the supply voltage (V
P
> 4.5 V)
are available, regulators 1 and 3 can be operated by
means of enable inputs (pins 10 and 4 respectively).
Regulator 1 has a hold output (open collector) indicating
that the output voltage of this regulator is settled (held
HIGH by external pull-up resistor). When the output
voltage of this regulator drops out of regulation (because
of supply voltage drop or high load) the hold output will go
LOW. The hold output signal is only valid when regulator 1
is enabled by its enable input (pin 10).
