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

0.25 V CC
0.4 V CC
V OC
– 0.25 V CC / (1.17 × Sens)
– 0.4 V CC / (1.17 × Sens)
Example: For ACS710KLATR-6BB-T, if required overcurrent fault switchpoint is 10 A, and V CC = 5 V, then the
required V OC can be calculated as follows:
V OC = 1.17 × Sens × I OC = 1.17 × 151 × 10 = 1767 (mV)
