ACS710
120 kHz Bandwidth, High-Voltage Isolation
Current Sensor with Integrated Overcurrent Detection
Setting 6BB and 10BB Versions
The VOC needed for setting the overcurrent fault switchpoint can
be calculated as follows:
VOC = 1.17 × Sens × | IOC | ,
where VOC is in mV, Sens in mV/A, and IOC (overcurrent fault
switchpoint) in A.
| Ioc | is the overcurrent fault switchpoint for a bidirectional (AC)
current, which means a bidirectional sensor will have two sym-
metrical overcurrent fault switchpoints, +IOC and –IOC .
See the following graph for IOC and VOC ranges.
IOC
0.4 VCC / (1.17 × Sens)

– 0.25 VCC / (1.17 × Sens)

Example: For ACS710KLATR-6BB-T, if required overcurrent fault switchpoint is 10 A, and VCC = 5 V, then the
required VOC can be calculated as follows:
VOC = 1.17 × Sens × IOC = 1.17 × 151 × 10 = 1767 (mV)
