8.3 Supply
The TDA8007BHL/C4 operates within a supply voltage range of 2.7 V to 6 V. The supply
pins are V

can create. V

that the contacts to the cards remain inactive during power-up and power-down. An
internal voltage reference is generated for use within the step-up converter, the voltage
supervisor and the V
The voltage supervisor generates an alarm pulse when V
operation. The alarm pulse length is defined by an external capacitor tied to pin DELAY
and is typically 1 ms per 2 nF.
The alarm pulse may be used as a reset pulse by the system microcontroller
(pin RSTOUT = high). It can also be used to block any spurious noise on card contacts
during the microcontrollers reset, or to force an automatic deactivation of the contacts in
the event of a supply drop-out (see
After power-on, or after a voltage drop, bit SUPL is set within register HSR and remains
set until register HSR is read-out outside the alarm pulse. Signal INT = low for the
duration that signal RSTOUT is active.
