Functional Features

Voltage Monitoring

The DS1810R-15+T&R continuously monitors the power supply voltage. It compares the monitored voltage with a user-defined threshold voltage.

Reset Function

When the monitored voltage falls below the set threshold, the DS1810R-15+T&R generates a reset signal. This signal can be used to initiate system resets or trigger specific actions in electronic devices.

Manual Reset Input

The MR pin allows for manual resetting of the device. When this pin is pulled low, it forces a reset regardless of the monitored voltage level.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring ensures reliable operation of electronic devices.
• Low power consumption prolongs battery life in portable applications.
• Wide operating voltage range enhances compatibility with various power supply configurations.
• Compact package size enables space-efficient integration into electronic designs.

Disadvantages

• Limited threshold voltage options may not cater to all voltage monitoring requirements.
• Lack of advanced features such as hysteresis adjustment limits customization possibilities.

Working Principles

The DS1810R-15+T&R operates by comparing the input voltage with the selected threshold voltage. If the input voltage drops below the threshold, the IC triggers a reset signal. The manual reset input provides an additional means to initiate a reset, independent of the monitored voltage.

Detailed Application Field Plans

The DS1810R-15+T&R finds applications in various electronic devices that require voltage monitoring and reset functionality. Some potential application fields include:

1. Microcontroller-based systems: The IC can ensure stable operation of microcontroller units by monitoring the power supply voltage and initiating resets if necessary.
2. Industrial automation: It can be used in industrial control systems to monitor critical voltages and trigger appropriate actions in case of voltage fluctuations.
3. Automotive electronics: The DS1810R-15+T&R can contribute to the reliable operation of automotive electronic systems by monitoring power supply voltages and initiating resets when needed.
