transistors How does the pull down resistor work in this ... up vote 0 down vote. When the left side of R1 gets disconnected then there is no current flow through R1 or R2 and that means that there will be no voltage drop across it. If there is no voltage drop across R2 the base level becomes 0v and the transistor is held in an off state. Pull up Resistor and Pull down Resistor Explained Open collector Outputs. Thus the transistor turns ON to pull the output to a LOW level. The size of the pull up resistor depends on the connected load and the voltage drop across the resistor when the transistor is OFF. When the output is LOW, the transistor must be able to sink the load current through the pull up resistor. How does a pull down resistor work answers How does a pull down resistor work? ... A pull up resistor is often used in an open collector circuit, where there is a transistor that can pull to down ground, but there is no transistor to pull ... How Pull Up and Pull Down Resistors Work in Logic Circuits You can use the same formula for calculating Pull Up resistor for any application. Pull Down Resistors: The Pull Up resistor keeps the pin “HIGH” if no input is connected; with Pull down resistor, it keeps the pin “LOW” if no input is connected. The pull down resistor is made by connecting the resistor to ground instead of Vcc. Pull up resistor Pull down resistor » Resistor Guide Pull down resistors work in the same manner as pull up resistors, except that they pull the pin to a logical low value. They are connected between ground and the appropriate pin on a device. An example of a pull down resistor in a digital circuit can be seen in the figure. Pull down resistors for MOSFETs | Electronics Forums Individual pull down resistors: One communal pull down resistor on a rail: The triggers are usually 12 14V and can be continuous sometimes for hours at a time so I want to minimise the current draw from grounding the triggers, hence the huge 10M resistors used which work in practice and only draw ~1mA through the 'short' created.
