The supply voltage range of the ATA5423/ATA5425/ATA5428/ATA5429 is 2.4V to 3.6V or 4.4V
to 6.6V.
Pin VS1 is the supply voltage input for the range 2.4V to 3.6V and is used in 1 Li battery applica-
tions (3V) using a single lithium 3V cell. Pin VS2 is the voltage input for the range 4.4V to 6.6V
(2 Li battery application (6V) and Base-station Application (5V); in this case, the voltage regula-
tor V_REG1 regulates VS1 to typically 3.25V. If the voltage regulator is active, a blocking
capacitor of 2.2 µF has to be connected to VS1.
Pin VAUX is an input for an additional auxiliary voltage supply and can be connected, for exam-
ple, to an inductive supply (see
with a rectifier or as in the application shown in
open.
Pin VSINT is the voltage input for the Microcontoller_Interface and must be connected to the
power supply of the microcontroller. The voltage range of V
