The present IP is a VCC Detector (VDT) circuit. It detects the battery voltage level. It will generate two flag signals, VBT21 and VBT36, when VBT3 reaches the trigger point. This IP contains two comparators and a reference voltage from internal bandgap. The output may be in the wrong voltage level during the power-up phase before the bandgap becomes stable.
