LED Flasher / PWM modules
Anthias contains a LED flasher / PWM modules that work in sleep modes. These functions are
controlled by the on-chip firmware.
POWER CONTROL, REGULATION AND RESET
Figure 5: Anthias Internal Regulation Block
Internal Switch-mode Regulator
Anthias has an internal switch mode regulator that generates the main rail from the battery
(VDD_BAT). The main rail supplies the lower regulated voltage to a further internal digital linear
regulator and also to the analog sections of the Anthias module. The switch mode regulator
generates typically an internal 1.35V.
Internal Low-voltage Linear Regulator
The integrated low-voltage VDD_DIG linear regulator powers the Anthias digital circuits. The input
voltage range is 0.65V to 1.35V. It can supply programmable voltages of 0.65V to 1.20V to the
digital area of the Anthias module. The maximum output current for this regulator is 30mA.
Important Note:
These regulators are for internal Unigen use only. See example circuit diagram
for Unigen recommended circuit connection.
