120 kHz Bandwidth, High Voltage Isolation

Current Sensor with Integrated Overcurrent Detection

1. Devices are programmed for maximum accuracy at VCC = 5 V. The device contains ratiometry circuits that accurately alter

the 0 A Output Voltage and Sensitivity level of the device in proportion to the applied VCC level. However, as a result of

minor nonlinearities in the ratiometry circuit, additional output error will result when VCC varies from the VCC level at

which the device was programmed. Customers that plan to operate the device at a VCC level other than the VCC level at

which the device was programmed should contact their local SEC sales representative regarding expected device accuracy

levels

2. Under these bias conditions.

3. RF(INT) forms an RC circuit via the FILTER pin.

4. This parameter can drift by as much as 0.8% over the lifetime of this product.

5. This parameter can drift by as much as 1% over the lifetime of this product.

6. See page 8 on how to set overcurrent fault switch point.

7. Switchpoint can be lower at the expense of switch point accuracy.

8. This error specification does not include the effect of noise. See the INCOMP specification in order to factor in the additional

influence of noise on the fault switch point.

9. Fault Enable Delay is designed to avoid false tripping of an Overcurrent (OC) fault at power-

up. A 15 μs (typical) delay will

always be needed, every time FAULT_EN is raised from low to high, before the device is ready for responding to any

overcurrent event.

10. During power-

up, this delay is 15 μs in order to avoid false tripping of an Overcurrent (OC) fault.
