The NEXSYS Current Sensor (CS1) is a Series A (4 pin) solid-state, low-side direct current (DC) sensor, developed to detect undercurrent and overcurrent conditions. The Current Sensor features fault-tolerant circuitry and architecture that provides low-drift sensing over the operating temperature range.
28V: Operating voltage (nom.), 2 mA current draw (max.).
GND: Continuous Ground required.
SENSE: Detects DC current. Current sensing includes a hysteresis band to prevent signal chatter.
OUTPUT Z: Open-drain output is Ground when active and High Impedance when not active. Output can be specified to activate when SENSE current is above or below the specified current level. The output load capacity is 0.5 A (Resistive).
The NEXSYS Current Sensor monitors overcurrent and undercurrent conditions from 10 mA to 1.0 A. Setpoint options are available in 10 mA increments from 10 to 90 mA and in 50 mA increments from 100 mA to 1.0 A.
To help system designers understand the potential of NEXSYS Component Technology, we have assembled a collection of Application Notes. The links below show example applications that utilize the Current Sensor component.
