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. The measurement setup used to measure RON is shown in the following figure. Voltage (V) and current (ISD) are measured using this setup, and RON is computed as shown in Figure 7-1 with RON = V / ISD:
