Applications of the TPD1S514-1 EVM

The TPD1S514-1 EVM is specifically designed for low-side switching applications. Its main application area includes automotive and industrial applications, where the conductors need to be switched safely, with low noise, at high currents and across a wide operating voltage range. This EVM is especially suitable for high side switching application in automotive engines and other motor control applications. It can also be used for high side DC/DC converter applications as well as general purpose switching. The circuit design of the module and accompanying software are both designed to accommodate a wide variety of user applications and to ensure reliability, minimizing noise, power losses, and thermal losses.

Features of the TPD1S514-1 EVM

The TPD1S514-1 EVM provides a stable platform for user applications. It is designed with a number of special features and advantages compared to other similar modules. Firstly, it is designed to provide a wide operating voltage range of 2.5V to 96V. It features both an adjustable current limit and an adjustable overcurrent protection scheme. The module also includes an integrated fail-safe clock signal that can be used to detect an overcurrent event and initiate an automatic fault reset. The module also features a wide range of input and output pin configurations to accommodate user needs and provides both isolated and ground sensing optocouplers.

Working Principle of the TPD1S514-1 EVM

The TPD1S514-1 EVM works on the principle of low side switching. It makes use of a low side MOSFET that is connected to an electrical load and actuated by a gate control signal. The gate control signal is generated by the module and is adjustable using the adjustable current limit and overcurrent protection features. The input voltage and the output voltage are both monitored by the module, and the internal clock signal is used to detect an overcurrent condition and initiate an automatic reset. The module also contains an optocoupler to ensure that the FET is not driven beyond the set parameters. If the FET is driven beyond the set parameters, the current protection and overcurrent protection features will be triggered.
