This Fuel level Monitor allows users to measure the fuel level using a resistive float sensor in the fuel tank. The project measures the fuel level and displays it on a 15-segment bar-graph display.  The project is Arduino-compatible and consists of ATMEGA328 controller. The...

This simple Arduino compatible project reads an RC PWM signal (1000μs to 2000μs) and provides 0 to 500Hz pulse output to drive a stepper motor. Step and Direction outputs are open collector types 5V signals. Both signals can directly drive LEDs of optocoupler of stepper drivers. The...

This is a Half-bridge module based on the LM5104 chip, which is a high-voltage gate driver. This High-Voltage Gate Driver is designed to drive both the high-side and the low-side N-channel MOSFETs in a synchronous buck configuration. The floating high-side driver can work with supply...

This is an automotive-grade self-oscillation 50% duty cycle half-bridge module built using the AUIR2085S chip from Infineon. The project consists of 2 x N-channel MOSFETs, and the module provides a primary side control solution to enable Half-Bridge DC-bus converters. The module is a...

This high-speed, isolated Undervoltage and Overvoltage detection project is implemented with a dual isolated window comparator with an adjustable threshold (AMC23C14). This circuit is designed for industrial field-supply applications where the controller side must detect whether the...

This is a simple Proportional, Integral (PI) temperature control amplifier. A complete thermoelectric cooler (TEC) controller can be created using this PI amplifier and OPA569 Power Op-Amp or other output amplifiers such as DRV591, DRV592 and DRV593. Proportional-integrator...

This design is intended to translate a small unipolar signal to a wide bipolar signal. A common application is to translate a 0 to 5V DAC output to a ±10V bipolar signal. All resistors are 1% but it is advisable to select 0.1% 20 ppm/°C resistors for good gain, offset accuracy, and...

This is a Smart power module project designed for Small Power AC Motors. The FNB40560 chip is the heart of the project. A compact inverter project is ideal for small power motors such as fans and pumps. H-bridge configuration can also be created for low current high-voltage brushed DC...
