The project presented here is a high-side switch (8 channels) with MOSFET output. The Arduino board consists of an Arduino-compatible microcontroller ATMEGA328 and TPD2015FN - 8 Channels MOSFET switch. All 8 inputs of TPD2015FN are TTL compatible. The project is suitable for driving...
Continue ReadingOver Current Trip Switch – Over Current Shutdown Relay
The project presented here is an over-current trip switch. It provides protection to a load when over current condition occurs. Basically, the project trips the relay when there is a short circuit or the load starts drawing much current. When the condition is favorable, press the...

The project described here is a very useful device for use with linear actuators. This controller prevents the actuator from reaching the physical movement limits of the actuator, thus it prevents burnout of motor and physical/mechanical damage to the actuator itself to the...
Continue ReadingHigh Current MOSFET Based Power Switch with Gate Driver
This power load switch project provides a simple and inexpensive method for power control. It is intended for driving a resistive or inductive load. A TTL logic signal from the system turns the load switch ON and OFF. The project consists of a low ohm N-Channel Power Trench MOSFET...
