8.14 Protections and limitations
There are several possible situations:
The switch between different modes of the DC-to-DC converter is done by the TDA8029 at
about V
The output voltage is fed to the V
all other card contacts.
The correct sequence during activation and deactivation of the card is ensured through a
specific sequencer, clocked by a division ratio of the internal oscillator.
Activation (bit START = 1 in register PCR) is only possible if the card is present (pin PRES
is HIGH) and if the supply voltage is correct (supervisor not active).
Pin PRES is internally biased with a current source of 45 A typical to ground when the
pin is open (No card present). When pin PRES becomes HIGH, via the detection switch
connected to V
allows direct connection of the detect switch to V
The presence of the card is signalled to the controller by the HSR.
Bit PR1 in register MSR is set if the card is present. Bit PRL1 in register HSR is set if PR1
has toggled.
During a session, the sequencer performs an automatic emergency deactivation on the
card in the event of card take-off, short-circuit, supply dropout or overheating. The card is
also automatically deactivated in case of supply voltage drop or overheating. The HSR
register is updated and the INT0_N line falls down, so the system controller is aware of
what happened.
