Functional Description
3.1
Power Supply (PS)
Figure 3-1.
Equivalent Circuit of Power Supply and Antenna Driver
The U2270B can be operated with one external supply voltage or with two externally-stabilized
supply voltages for an extended driver output voltage or from the 12V battery voltage of a vehi-
cle. The 12V supply capability is achieved via the on-chip power supply (see Figure 3-1). The
power supply provides two different output voltages, V
S and VEXT.
V
S is the internal power supply voltage for everything except for the driver circuit. Pin VS is used
to connect a block capacitor. V
S can be switched off by the STANDBY pin. In standby mode, the
chip’s power consumption is very low. V
EXT is the supply voltage of the antenna’s pre-driver.
This voltage can also be used to operate external circuits, such as a microcontroller. In conjunc-
tion with an external NPN transistor, it also establishes the supply voltage of the antenna coil
driver, DVS.
