Low Voltage Lead Acid Battery Disconnect board – Prevents Deep Discharge Of 12V Lead Acid Battery
https://www.electronics-lab.com/low-voltage-lead-acid-battery-disconnect-board-prevents-deep-discharge-of-12v-lead-acid-battery/
This project helps to optimize the 12V lead-acid (SLA) battery life as it prevents the battery from going into deep discharge. It is very important to disconnect the load before the battery enters into deep discharge as this may destroy or damage the battery cells. The circuit shown here turns off the load before the […]
High Side Switch with Input Overvoltage and Overcurrent Protection
https://www.electronics-lab.com/high-side-switch-with-input-overvoltage-and-overcurrent-protection/
The project here is a 48V protected, high side switch designed to switch a 5A output load from input voltages from 8V to 48V. The circuit helps the user to easily ON/OFF the high current and voltage load with over-voltage lockout and over-current protection. The wide input range and low shutdown current (1μA typical) make […]
3W Stereo Differential Input CLASS-D Audio Amplifier with UP/DOWN Volume
https://www.electronics-lab.com/3w-stereo-differential-input-class-d-audio-amplifier-with-up-down-volume/
The circuit presented here is a 3W stereo audio amplifier with memory UP/DOWN volume control. The project is based on PAM8408 IC from Diode Incorp which is a filter-less class-D amplifier with high SNR and Differential input which helps eliminate noise. Two tactile switches are provided to control the UP/DOWN volume in 32-steps and it […]
