DS1834AS+

The DS1834AS+ series of supervisory circuits are intended to provide reliable system reset and supply-monitoring functions, allowing device parameter and application-specific requirements to be met with minimal component count.

The DS1834AS+ provides a three-state reset output, reset enable and power-on reset circuits. The three-state reset output allows a system reset signal to be distributed to multiple devices. The reset enable input can enable or suspend reset timing and the power-on reset circuit resets the system upon system start-up.

The DS1834AS+ series of supervisory circuits offers reset options for multiple reset TTL-compatible push buttons, printed circuit board test points and other sources. In addition, the DS1834AS+ offers two preset thresholds which are used to set a minimum acceptable voltage threshold to indicate proper power-up, safe operation and reset timing. The DS1834AS+ also features a pulsed reset indicator to indicate the status of the reset signal.

The DS1834AS+ series of supervisory circuits are available in a small 8-pin SOIC package for space-constrained applications, as well as a 20-pin DIP package for more general-purpose applications. The reset outputs are open-drain and can be connected to LEDs, relays and/or other systems.

The working principle of the DS1834AS+ series of supervisory circuits is simple. The preset minimum voltage thresholds are used to monitor the power supply voltage, while the reset enable input can be used to suspend or enable reset timing. When the power supply voltage drops below the preset voltage, a reset signal is generated and the reset output will be activated.

Once the reset output has been activated, the reset indicator output will pulse to indicate that the reset has been triggered and the device is in its reset state. The reset output of the DS1834AS+ will remain active until the voltage is restored to above the preset threshold. Once this occurs, the pulsed reset indicator output will be deactivated and the reset output will be released.

The DS1834AS+ series of supervisory circuits provide reliable system reset and supply-monitoring functions for multiple device applications, ensuring safe and reliable operation of system devices. The DS1834AS+ can be used in a variety of applications, from communications and consumer electronics to automotive and industrial electronics.

In communications and consumer electronics applications, the DS1834AS+ can be used for power supply monitoring and reseting purposes, as well as for switching off loads in the event of a power outage or mains failure.

In automotive and industrial applications, the DS1834AS+ can be used to monitor and reset multiple power supply, providing a reliable and cost-effective solution. Additionally, it can be used to switch off loads in the event of a power outage or even in the event of a fault in the system.

The DS1834AS+ series of supervisory circuits is a reliable and cost-effective solution for providing system reset and supply-monitoring functions. With its simple circuitry and versatility, the DS1834AS+ can be used for power supply and reset monitoring in multiple device applications, ensuring safe and reliable operations.
