Two main functions - Analog signal output with an operational amplifier for A/D conversion Provides an analog output signal that is conditioned by an operational amplifier to support accurate analog-to-digital conversion. - Presetable current limit via a switch signal with visual indication The device includes a switch output that allows the current limit threshold to be preset. When the actual current exceeds the preset limit, the switch output changes from a low level to a high level, and an LED indicator shows the event. Key benefits - Easy integration with measurement and control systems The analog output is conditioned for reliable ADC sampling, reducing the need for external signal conditioning. - Clear threshold monitoring A configurable current limit lets you define the protection or monitoring point, with a definitive switch-level change when exceeded. - Immediate visual feedback The LED indicator provides a quick, at-a-glance status of current threshold events. - Simple digital and analog interfacing The combination of an analog output for measurement and a binary switch signal for threshold signaling simplifies wiring to both ADC inputs and control logic or microcontroller circuits. 2-3 practical use scenarios - Bench power supply protection and monitoring Attach to the supply’s output current path to monitor real-time current. When the load current surpasses the preset limit, the switch output flips to high and the LED lights, triggering logging or protective actions in the control system. - Battery charging circuits Use the presettable current limit to guard against overcurrent during charging. The switch output provides a clear alert to the charger controller, while the analog output provides a continuously monitored signal for diagnostics or display. - Industrial motor drive protection Integrate with motor drives or protection relays to detect overcurrent conditions. The device’s dual signaling lets the control system respond quickly while the LED offers local status indication. Notes - The description reflects the device’s two core capabilities: an analog output with an op-amp for A/D readiness, and a switch-style current limit indicator with an LED indication. - No additional external components are required to interpret the standard low-to-high switch transition and the accompanying LED status.
