概述

The TPT485N is a low-power RS-485 transceiver with automatic bus-polarity correction and transient protection.

Upon hot plug-in, the device detects and corrects the bus polarity within the first 100 ms of bus idling. On-chip transient protection protects the device against IEC61000 ESD and EFT transients. This device has robust drivers and receivers for demanding industrial applications. The bus pins are robust to electrostatic discharge (ESD) events, with high levels of protection to Human-Body Model (HBM), Air-Gap Discharge, and Contact Discharge specifications. The device combines a differential driver and a differential receiver, which operate together from a single 5-V power supply. The driver differential outputs and the receiver differential inputs are connected internally to form a bus port suitable for half-duplex (two-wire bus) communication. The device features a wide common-mode voltage range making the device suitable for multi-point applications over long cable runs.

The TPT485N is available in SOP8 package, and is characterized from –40°C to 125°C.
