In this paper, the authors present a constant voltage constant current readout circuit for Ion-Sensitive Field-Effect Transistor (ISFET). The study and investigation of ISFET performance using linear ...

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

An idea in an earlier blog is to make a pwm interface that can accept 5, 12 and 24V pulse streams. That one uses a bunch of resistors and has three separate inputs. Below that, wise commenter DB ...

A current-limiting circuit is often needed to protect the most expensive parts of the circuit from transients such as current spikes, which occur when a power supply is driving a large capacitive load ...

Convenience lighting for passengers during entry and exit is a standard feature on all modern passenger cars. The typical method of operation is to power the lighting system when a door is open, via a ...

In designs using multiple LED strings such as brake lights, daytime running lights, rear lights and other automotive lighting applications, current-balancing circuits supply equal current to all LED ...

TOKYO--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation ("Toshiba") has added “TB67S539FTG” to its lineup of stepping motor driver IC series that support constant current control, for ...

The LM334 is not only an adjustable current source, but it is also a rectifier. Right on the front page of the TI data sheet are the words: “Reverse applied voltages of up to 20V will draw only a few ...

Download Volume 3 of the Bob Pease eBook series. Recently, a guy asked me how to draw a constant 1.00 mA from a node of a circuit. Of course, he did not tell me what volts, ohms, or frequency. But, he ...

KAWASAKI, Japan--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation ("Toshiba") has expanded its lineup of stepping motor driver ICs with the launch of “TB67S549FTG,” a stepping motor ...
