PRODUCTION DATA
The on-resistance of a device is the ohmic resistance between the source (Sx) and drain (D) pins of the device. The on-resistance varies with input voltage and supply voltage. The symbol RON is used to denote on-resistance. Figure 6-1 shows the measurement setup used to measure RON. Voltage (V) and current (ISD) are measured using the following setup, where RON is computed as RON = V / ISD:
