AS6200
Temperature Sensor
General Description
The AS6200 IC is a high accuracy temperature sensor system
that communicates via a 2 wire digital bus with other devices.
It consists of a Si bandgap temperature sensor, an ADC and a
digital signal processor.
It has a very high temperature accuracy (±0.4°C for AS6200) and
an ultra-low power consumption (low operation and quiescent
current) which makes it ideally suited for mobile/battery
powered applications.
The AS6200 is an easy to integrate and use solution, featuring
an factory calibrated sensor, integrated linearization and the
possibility to use 2 different I²C addresses, enabling to use two
AS6200 devices on one bus.
Additionally the AS6200 temperature sensor system also
features an alert functionality, which triggers e.g. an interrupt
to protect devices from excessive temperatures.

In
Figure 2
a typical application of the AS6200 is shown. It is
connected via a serial bus (I²C) with a microcontroller.
The sensor system is also connected to the microcontroller via
the “Alert” pin which can be used to trigger events in case the
temperature exceeds defined limits.

all relevant blocks of the AS6200 temperature sensor
are shown. The sensing element is a Si bipolar transistor.
The analog signal is transformed by the A/D converter in a
digital signal which is processed by the DSP and written into
the registers.
The data in the register can be accessed by the serial bus (I²C).
