Microcontroller is a chip designed to perform specific task/application. Microcontroller consists of CPU (microprocessor),RAM,ROM,I/O ports,timers,counters etc. ReferMicrocontroller tutorialwhich covers microcontroller architecture, interfacing, timers, interrupts, serial communication and microcontroller kit ve...
And the same way open collector works is the same way that open drain works. The only difference is the an open collector uses a bipolar junction transistor (BJT), while an open drain uses a FET transistor. To see how an open collector circuit is connected, see the building of an LM311...
Open-Drain/Open-Collector Outputs: In some designs, the GPIO might be used as an open-drain or open-collector output. In such cases, the external circuitry or another GPIO might provide the pull-up resistor, so the internal pull-up resistor is not used. High-Impedance Input: For certain ...
if a power switch gets stuck in either the "on" or "off" position, it can cause problems. if it gets stuck in the "on" position, the device will remain powered, which can drain the battery or consume unnecessary energy. if it gets stuck in the "off" position, the device won't ...

/INT is an open-drain signal; you can just use a pull-up to 3.3 V without a translator. Up+1TrueDown Yigal BenZeev2 年多前in reply toClemens Ladisch Prodigy30points Are you suggesting that thePCF8574 will operate on 5V, yet the /INT output will be tied to 3.3V pu...
high when there is no current flowing and low when the current is transmitted. However, you should be aware that MOSFETs complete with microcontrollers may require 10-15 Gate Source potential difference for the lowest level of Drain source resistance with the microcontroller operating on 5v or 3.3...
L293D is a microcontroller, isn't it? The L293D chip is a stepper motor driver. L293D is housed in a 16-pin DIP package that includes a bipolar H-bridge circuit and all holes are n-type. How to use L293D? Place the L293D in the center of the breadboard, with half of the pins...
However, the open-drain pin of a RESET IC has a large ON resistance, which means it takes a long time to discharge an external device. ICs specialized in controlling power-off sequences Discharge IC As indicated by its name, a discharge IC is used to discharge output capacitance. Many ele...
When no voltage is applied across the gate terminal, the channel becomes a wide-open path for electrons to flow. Therefore maximum current flows from the source to the drain terminal. The amount of current flow is determined by the potential difference between source and drain terminals and the...
