MAXQ3180 Maxim, MAXQ3180 Datasheet - Page 40

• Manufacturer Part Number: MAXQ3180
• Description: The MAXQ3180 is a dedicated electricity measurement front-end that collects and calculates polyphase voltage, current, power, energy, and many other metering and power-quality parameters of a polyphase load
• Manufacturer: Maxim

Low-Power, Multifunction, Polyphase AFE
This signed register contains the angle, as a fraction of one radian, to add to the measured phase angle when the
measured current is between the values given in I1THR and I2THR. This signed value ranges from -0.5 radian (at a
value of 0x8000) to +(0.5 - 2
This signed register contains the angle, as a fraction of one radian, to add to the measured phase angle when the
measured current is below the value given in I2THR. This signed value ranges from -0.5 radian (at a value of 0x8000)
to +(0.5 - 2
This register specifies the fraction of full-scale current that is declared to be an overcurrent condition. When X.IRMS
exceeds this level for one DSP cycle, the OCF flag in the X.FLAGS register is set. If the OCM flag is set in the
X.MASK register, setting the OCF flag will cause the interrupt bit OC to be set in the IRQ_FLAG register. If the inter-
rupt is enabled, the interrupt pin is driven active. Full scale is represented by 0x10000. The maximum value for this
register is 0xFFFF.
