Multiple output voltage regulators
FUNCTIONAL DESCRIPTION
The TDA3601Q is a multiple output voltage regulator with
six fixed voltage regulators. Three, logical switch
controlled, voltage regulators (numbers 4 to 6) are
available, and one non-switchable voltage regulator
(number 1). In addition, there are two further regulators
(numbers 2 and 3), which are controlled by supply
voltages VP1 and VP2 (Schmitt trigger).
Regulator 1 is not affected by load dump or thermal
shutdown. Regulators 2 to 6 are supplied by VP2; they can
therefore be switched of by an ignition switch, for example.
An internal bandgap voltage reference, which provides a
reference voltage for each independent regulator, is
supplied by V
regulator 1.
A VP2 sense circuit outputs a logical high when the V
voltage rises through V
voltage falls through V
The supply voltage VP1 is sensed by an out-of-regulation
Schmitt trigger.
. This supply voltage VP1 also supplies
P1
, which remains high until the V
thr
.
thf
P2
P2
TDA3601Q
TDA3601AQ
When this voltage drops below 5.95 V typical, the reset
output is disabled, to prevent a microprocessor being
disturbed by a too-low supply voltage. An out-of-regulation
condition is indicated by a logical low and an in-regulation
condition indicated by a logical high.
The ‘Power On’ switch low will disable regulator 2 and 3
outputs. In addition, the logic switch will be disabled, so
that regulators 4 to 6 are switched off. When both
-sense and out-of-regulation are high, the ‘Power On’
V
P2
will be high, so that the logic multiplexer and regulators 2
and 3 are enabled. Regulators 4 to 6 can now be selected
by the multiplexer.
Re-triggerable one-shot circuits produce a RESET (open
collector output) when VP1 is available (40 ms delay
signal), or when both VP1 and VP2 are available (100 µs
pulse). RESET will be held in a constant high state when
the supply voltage VP1 is less than 5.5 V (5.95 V typical).
The TDA3601 has a RESET output, but the TDA3601A
has an inverted RESET output (RESET).

SOLDERING
Introduction
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our
“IC Package Databook”
Soldering by dipping or by wave
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.
(order code 9398 652 90011).
TDA3601Q
TDA3601AQ
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (T
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
Repairing soldered joints
Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.
