PRODUCTION DATA.
The on-resistance of a device is the ohmic resistance between the source (Sx) and drain (Dx) pins of the device. The on-resistance varies with input voltage and supply voltage. The symbol RON is used to denote on-resistance. The measurement setup used to measure RON is shown in Figure 27 . Voltage (V) and current (IDS) are measured using this setup, and RON is computed as shown below with RON = V / ISD:
