Renesas offers OVP transceivers with wide supply and common-mode ranges at very attractive pricing. Competing devices, such as Competitor T shown here, claim operation down to 3 V yet already show an inferior output drive capability of VOD = 0.85 V across a differential load of RL = 54 Ω at VCC = 3.3 V. In strong contrast, Renesas' ISL3245xE family of OVP transceivers provides almost twice as much differential output voltage with VOD = 1.5 V (Figure a). Figure b shows the ISL3245xE maintaining a VOD close to 1.5 V across the standard common-mode range while providing high output drive towards the outer limits of ±20 V. Although specified for a much narrower common-mode range, Competitor T’s VOD comes nowhere near the 1.5 V minimum (dotted line) for the entire range. Furthermore Competitor T does not provide true 3 V operation but stops operating at 3.15 V (Figure c). This is only 5% below the nominal 3.3 V level, thus calling for a much tighter output tolerance of the linear voltage regulator providing the transceiver supply. Renesas' ISL3245xE transceivers outperform the competition by operating down to a minimum supply of 2 V, which ensures true 3 V operation and allows for a wider tolerance of the regulator output voltage.
