Vreg U/I Monitoring
Purpose
Obtain continuous information on the temperature, regulator voltage and current of the card regardless of its current state. This information is compared to pre-set values for possible shutdown of the Charge pump and input voltages. The slow control voltage powering the micro-controller (uC) is neither monitored or interrupted.
