Webspecified threshold. This reset signal is the open drain output in need of a pull-upor pull-downresistor. An SVS can also have an open drain PFO output that asserts if some voltage in the system drops below a specified threshold. In a power converter, a PG output is routinely used to drive the enable input of a subsequent IC. A PG Web27 de jun. de 2016 · The open collector (BJT) or open drain (FET) is essentially a SPST switch connecting the IC pin to ground. If the switch is closed, then the voltage on the pin (and the I²C line) is about 0 volts. If any switches are closed (if any pins of any ICs are connected to the same SDA or SCL line), the voltage on the line is about 0 volts. grassroots farmers coopWebThe interrupt output can be configured to activate under two conditions (mutually exclusive): 1. When any input state differs from its corresponding input port register state. This is used to indicate to the system master that an input state has changed. 2. When an input state differs from a pre- configured register value (DEFVAL register). chlap online serialovo
