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 VP1. This supply voltage VP1 also supplies
regulator 1.
A VP2 sense circuit outputs a logical high when the VP2
voltage rises through Vthr, which remains high until the VP2
voltage falls through Vthf.
The supply voltage VP1 is sensed by an out-of-regulation
Schmitt trigger.
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
VP2-sense and out-of-regulation are high, the ‘Power On’
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).
