Functional Features

Voltage Monitoring

The DS1810R-10+T&R continuously monitors the power supply voltage and compares it to a user-defined threshold. This feature ensures that the system operates within safe voltage limits.

Reset Generation

When the monitored voltage falls below the specified threshold, the DS1810R-10+T&R generates an active-low reset signal. This signal can be used to initiate system resets or trigger specific actions in response to voltage fluctuations.

Manual Reset Input

The MR pin allows for manual resetting of the system. When this pin is pulled low, the DS1810R-10+T&R generates a reset signal regardless of the monitored voltage level.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring ensures system stability.
• Low power consumption extends battery life in portable devices.
• Wide operating voltage range enhances compatibility with various power sources.
• Compact form factor enables easy integration into space-constrained applications.

Disadvantages

• Limited threshold voltage options may not cater to all voltage monitoring requirements.
• Lack of additional features beyond voltage monitoring and reset generation.

Working Principles

The DS1810R-10+T&R operates by comparing the power supply voltage against the user-defined threshold. If the voltage drops below the threshold, the IC generates a reset signal. The manual reset input allows for immediate system resets, irrespective of the voltage level.

Detailed Application Field Plans
