Open-drain interrupt output

WebIf at least one of the outputs is in logic 0 state (active), the circuit sinks the current and brings the line to low voltage. You can use open-drain output if you are connecting multiple devices to a bus. For example, you can use the open-drain output for system-level control signals that can be asserted by any device or as an interrupt.

Web5 de abr. de 2024 · 1. Open-collector (or open-drain) outputs are needed for many reasons. For example, many devices can pull the same signal low to indicate they need attention, but since no device pushes high, only a resistor does, so they can coexist on … 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.

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.
