16 / 43 page 8 Detailed Description 8.1 Overview 8.1.1 On-Resistance 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 below. Voltage (V) and current (ISD) are measured using this setup, and RON is computed as shown in Figure 8-1 with RON = V / ISD: V D V S I SD Sx Figure 8-1. On-Resistance Measurement Setup 8.1.2 Off-Leakage Current There are two types of leakage currents associated with a switch during the off state: 1. Source off-leakage current. 2. Drain off-leakage current. Source leakage current is defined as the leakage current flowing into or out of the source pin when the switch is off. This current is denoted by the symbol IS(OFF). Drain leakage current is defined as the leakage current flowing into or out of the drain pin when the switch is off. This current is denoted by the symbol ID(OFF). The setup used to measure both off-leakage currents is shown in Figure 8-2. VDD VDD S0 GND VS S7 D VD A ID (OFF) VDD VDD S0 GND VS S7 D VD A Is (OFF) S6 S6 Figure 8-2.
