The device contains a 34mΩ low RON N-MOSFET controlled by the ON pin. When the power supply is turned on for the first time, a smart pull-down resistor is used to float the ON pin until the system is stable. Once the ON pin reaches a high voltage (> VIH), the pull-down resist...
have tasmota on esp-12f running, my power meters sending 800Imp/KWh. I have a switch gpio attached to S0 output (pull down resistor) and tasmota is counting every impulse and sending it to my mqtt server (there i have attached node-red and influxdb für stats and counting). Every Impul...

As I have no starter/ignition battery in the car, I use this GPIO to pull down the latch input through a 100R resistor. This pull down is only momentary as once the 2N3904 transistor base voltage drops, the P-Channel MOSFET switches off and everything goes back to sleep. The reason ...
To keep the VIGN input Wfrom floating, a 10k pull–down resistor to GND should be used. The VIGN pin has a 3.0 V threshold and 1.0 volt of hysteresis. VIGN is designed to operate up to +26.5 volt battery while providing reverse battery and +45 volt load dump protection. The input ...
The clamp circuit is coupled to the gate of the PMOS. In one embodiment, the clamp circuit has an RC time constant and is comprised of an NMOS, a capacitor, and a pull-down resistor.GREGORY J. SMITH
When configured as an input, a weak internal pull-up or pull-down resistor can be enabled. By default, these signals are configured as inputs with an internal pull-up resistor enabled. These signals are reset back to inputs upon the assertion of the SYS_RST_L signal. — Broadcom 56980-...
As seen by reference to the signal path over which the VREF_1 signal travels, the reference voltage to the first handpiece travels each signal path includes a pull down resistor 592. A surge suppressor 594 is connected in parallel across resistor 592. The VREF_x signal is then applied to ...
