Heavy duty battery charger
The operational amplifier A1 directly drives the VN64GA with the error signal to control the output voltage. The peak rectifier D1 and capacitor C1 supply the error amplifier A1 and the reference zener. This additional drive voltage must exceed its...
2.5 V Lead-Acid Battery Charger
The following circuit illustrates a 1.5 V Lead-Acid Battery Charger Circuit Diagram. Features include a comparator output that controls the voltage regulator.
The 1.5 V Lead-Acid Battery Charger Circuit is designed to efficiently charge lead-acid batteries while ensuring optimal voltage regulation...
Controlling high-current circuits
Digital output from a microcontroller is typically a low-amperage signal. For example, when a pin is set HIGH on the microcontroller (in Wiring/Arduino, it is digitalWrite(somePin, HIGH);), the voltage from that pin is usually +3.3V or +5V, with the current...
GSM Remote Control 2 IN and 2 OUT Part 2 Schematic
The control of the system is managed by a Microchip PIC18F46K20-I/PT microcontroller, which is programmed with firmware to oversee the activity of the GSM/GPRS module, monitor the logic conditions of two opto-isolated inputs, and send commands to two relays within...
How to Design Battery Charger Applications that Require External Microcontrollers and Related System-Level Issues
Application note on designing linear and switch-mode (switching DC-DC converter current source) battery charger applications that require external microcontrollers and related system-level issues for notebook computers.
The application note provides guidance on the design of both linear and switching DC-DC converter...
Digital Main Voltage Indicator
Continuous monitoring of mains voltage is essential in various applications, including manual voltage stabilizers and motor pumps. Although an analog voltmeter is cost-effective, it has several drawbacks due to its moving parts and sensitivity to vibrations. The solid-state voltmeter circuit...
