Features
Overview
•
•
•
•
ATmega16HVB/32HVB get its voltage supply through the VFET terminal. Operating range at the
VFET terminal is 4 - 25V. The on-chip LDO regulator regulates the VFET terminal down to 3.3V,
which is a suitable supply voltage for the internal logic, I/O lines and analog circuitry.

Figure 23-1. Voltage Regulator.
To ensure safe operating condition the Voltage Regulator has built in protection mechanisms to
protect the internal circuitry if the voltage drops on either the input or output terminal. The Regu-
lator Monitoring includes
• Battery Pack Short Detector
• Black-out Detector
An external decoupling capacitor (CREG) of minimum 1 µF is needed to ensure stable regulator
operation. The same capacitor also serves as a reservoir capacitor to ensure that the chip is
able to operate for some time without voltage at the VFET terminal.
