Supply Voltage Regulator
Antenna Sensor
Atmel ATR4253
The driving voltage for an external power transistor is provided by an integrated regulator
circuit.
An overvoltage protection circuit detects overvoltage condition and switches off the amplifier
and AGC circuit in order to reduce current consumption and avoid thermal overload.
The Atmel
connected to the amplifier module. If no antenna is detected, the amplifier and AGC circuit are
switched off to signal this error via supply current reduction to the unit that provides and moni-
tors the supply current for the antenna amplifier (e.g., the car radio).

ATR4253 provides a built-in antenna sensor that detects if the antenna is properly
