This IP is a Voltage Detector (VDT) circuit for power management application. When the supply voltage (AVDD33) increases above the detection level (VTHR), the output VOK33 will assert a logical high (VOH). When AVDD33 decreases below the detection level (VTHF), the output VOK33 will assert a logical low (VOL). This IP cannot operate stand-alone. It needs a 1.2V reference and 1.75uA bias current from another VeriSilicon IP, GSMC18_PRG_03.
