A GdS cell serves as one leg of a bridge circuit. Potentiometer R6 in another leg establishes the trip point. Potentiometer R5 allows for hysteresis adjustment to prevent chattering or hunting of the relay. The light level must increase...
CAT3606 is a high-efficiency white LED driver. This adjustable charge pump is suitable for general-purpose, large-panel, flicker-free white LED backlighting and dual-display systems. The CAT3606 inductor boost circuit can replace conventional high-brightness backlighting requirements, thereby simplifying system design. It...
A milliamp meter can function as a voltmeter by incorporating a series resistance. The required resistance is calculated by dividing the full-scale voltage reading by the full-scale current of the meter movement. For instance, using a 1 milliamp meter...
This circuit also prevents the shutdown circuit of the IR2161 from operating in the normal way; therefore, an external SCR-based protection circuit needs to be added. The IR2161 is a high-voltage, high-speed driver designed for driving IGBTs and MOSFETs in...
In a circuit transistor tester schematic, there is a circuit that can indicate the condition of a transistor using two LEDs. A good NPN transistor... The circuit transistor tester is designed to evaluate the functionality of both NPN and PNP...
The image illustrates a circuit that utilizes a linear potentiometer (or linear Hall element) to control the PWM generation for two chassis drive motors in a gamepad or joystick used in model aircraft. J1 represents the handle of the...
