Figure 28. Typical Plot of Differential Measurement Method After Calibrating for Offset at Room
Temperature
The AIC28 supports programmable auto-temperature measurement mode, which can be enabled using control
register 0CH/page 1. In this mode, the AIC28 can auto-start the temperature measurement after a
programmable interval. The user can program minimum and maximum threshold values through a register. If
the measurement goes outside the threshold range, the AIC28 sets a flag in the read only control register
0CH/page 1, which gets cleared after the flag is read. The AIC28 can also be configured to send and active
high interrupt over GPIO1 by setting D9 in control register 0CH/page 1. The duration of the interrupt is
approximately 2 ms.
Battery Measurement
An added feature of the AIC28 is the ability to monitor the battery voltage on the other side of a voltage regulator
(dc/dc converter), as shown in Figure 29. The battery voltage can vary from 0.5 V to 6 V while maintaining the
analog supply voltage to the AIC28 at 3.0 V to 3.6 V. The input voltage (VBAT) is divided down by a factor of
5 so that a 6.0 V battery voltage is represented as 1.2 V to the ADC. In order to minimize the power consumption,
the divider is only on during the sampling of the battery input.
If the battery conversion results in A/D output code of B, the voltage at the battery pin can be calculated as:
V

VREF
Where:
N is the programmed resolution of A/D
VREF is the programmed value of internal reference or the applied external reference.
