8 Detailed Description

8.1 Overview

Figure 8 shows that the device driver output (OUT) can be used in a push-pull, high-side, or low-side

configuration using the enable (EN) and transmit data (IN) input pins. OUT can drive resistive, large capacitive or

large inductive loads.

TIOS101 and TIOS101-x devices have integrated IEC 61000-4-4/5 EFT and surge protection. In addition,

tolerance to ±65-V transients enables flexibility to choose from a wider range of TVS diodes if an application

requires higher levels of protection. These integrated robustness features will simplify the system-level design by

reducing the external protection circuitry.

These devices implement protection features for over-current, over-voltage and over-temperature conditions. The

devices also provide a current-limit setting of the driver output current using an external resistor.

The TIOS101-x devices derive the low voltage supply from the typical 24 V industrial supply via an internal linear

regulator to provide power to the local controller and sensor circuitry.
