Product Specifications

Technical details and manufacturing context for Active Load

Definition
An active load is a specialized electronic component within Pin Electronics/Driver-Sensor Cards used to emulate various electrical load conditions (resistance, capacitance, inductance) on output drivers or sensors during testing, calibration, and validation. It provides precise, programmable load characteristics to verify circuit performance under different operating scenarios.
Working Principle
Utilizes active semiconductor devices (such as MOSFETs or BJTs) controlled by feedback circuits to dynamically adjust its impedance, mimicking the behavior of passive loads while offering faster response, greater precision, and programmability for testing purposes.
Common Materials
Semiconductor Silicon, Copper, FR-4 (PCB Substrate)
Technical Parameters
  • Programmable range for resistance, capacitance, and inductance simulation. (Ω, F, H) Customizable
Components / BOM
  • Power MOSFET Array
    Primary switching element that dissipates power and controls current flow to simulate the load.
    Material: Semiconductor Silicon
  • Control IC / Op-Amp
    Provides the feedback and control signals to the MOSFETs based on the programmed load parameters.
    Material: Semiconductor Silicon
  • Sense Resistor Part
    Measures the current flowing through the load for closed-loop control.
    Material: Manganin or Constantan Alloy
  • Heat Sink
    Dissipates thermal energy generated by power dissipation in the MOSFETs.
    Material: Aluminum Alloy
