•
ATmega16HVB/32HVB features a highly accurate low power On-chip Bandgap Reference Volt-
age, VREF of 1.100V. This reference voltage is used as reference for the On-chip Voltage
Regulator, the Brown-out Detector, the internal Cell Balancing, the Battery Protection, the V-
ADC and the CC-ADC.
Figure 21-1. Bandgap Reference Voltage
In addition to the Bandgap Reference Voltage, the Voltage Reference includes a Calibration Unit
that enables run time calibration of the Reference Voltage, an On-chip temperature sensor for
monitoring the die temperature, and a Bandgap Short Detector to detect short circuit conditions
on the external VREF pin for highest safety.
