SC212KSIT
120 kHz Bandwidth, High Voltage Isolation
Current Sensor with Integrated Overcurrent Detection
Features and Benefits
1. Industry-leading noise performance with greatly improved bandwidth through proprietary
amplifier and filter design techniques
2. Small footprint package suitable for space-constrained applications
3. 1 mΩ primary conductor resistance for low power loss
4. High isolation voltage, suitable for line-powered applications
5. User-adjustable Overcurrent Fault level
6. Overcurrent Fault signal typically responds to an overcurrent condition in < 2 μs
7. Integrated shield virtually eliminates capacitive coupling from current conductor to die due to
high dV/dt voltage transients
8. Filter pin capacitor improves resolution in low bandwidth applications
9. 3 to 5.5 V, single supply operation
10. Factory trimmed sensitivity and quiescent output voltage
11. Chopper stabilization results in extremely stable quiescent output voltage
12. Ratiometric output from supply voltage
Package: 16-pin SOIC Hall Effect IC Package (suffix SI)
Typical Application Circuit

Functional Block Diagram
Terminal List Table, Latching Version
Number Name
Description
1 through 4
Sensed current copper conduction path pins. Terminals
IP+ for current being sensed; fused internally, loop to IP
pins; unidirectional or bidirectional current flow.
5 through 8
Sensed current copper conduction path pins. Terminals
IP– for current being sensed; fused internally, loop to IP+
pins; unidirectional or bidirectional current flow.
9 GND Device ground connection.
Voltage Reference Output pin. Zero current (0 A)
10 VZCR reference; output voltage on this pin scales with VCC .
(Not a highly accurate reference.)
11
FILTER
Filter pin. Terminal for an external capacitor connected
from this pin to GND to set the device bandwidth.
Analog Output pin. Output voltage on this pin is
12 VIOUT proportional to current flowing through the loop
between the IP+ pins and IP– pins.
Overcurrent Fault pin. When current flowing
13
between IP+ pins and IP– pins exceeds the
FAULT overcurrent fault threshold, this pin transitions to a
logic low state.
14 VCC Supply voltage.
15
VOC
Overcurrent Input pin. Analog input voltage on this
pin sets the overcurrent fault threshold.
Enables overcurrent faulting when high. Resets
16 FAULT_EN
FAULT when low.

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.
