DS1707EUA+T&R

The DS1707EUA+T&R is a versatile and cost-effective supervisor circuit that provides both reset pulse width control and temperature-sensing capability. It offers designers greater system-level functionality and accuracy in the most cost-effective design implementation. The DS1707EUA+T&R is ideal for use in battery scalability, over-temperature detection, and power management applications, where providing both reset and temperature-sensing capabilities help ensure overall system reliability.

In its basic applications, the pin-programmable DS1707EUA+T&R is designed to detect over-voltages, short circuits, and ground shorts; ensure device sequencing, sequencing delays, and sequencing accuracy; monitor the voltage drop across power buses; and monitor other specified voltages or currents. For high temperature applications, the device offers an easy-to-use, programmable thermal sensing range of ­55°C to 125°C. This ensures accurate power-on reset and power-off voltages in any environmental condition.

The DS1707EUA+T&R has a variety of features that make it an ideal choice for power management applications, such as output voltage and power sequencing, battery scalability and thermal monitoring. Its output voltage and power sequencing capabilities enable systems to support multiple power domains, and its configurable reset pulse width widens the reset period, ensuring more reliable operation in the event of a voltage drop or voltage spike induced by system faults. In addition, its battery scalability feature has a temperature-independent power-up sequence reducing battery consumption.

For thermal monitoring, the DS1707EUA+T&R offers a user-programmable thermal monitoring window. With the availability of temperature monitoring options, the device can monitor any temperature that falls outside the threshold window and provide an alarm signal. The alarm signal initiates a reset sequence that can either terminate the power supply or switch it off as necessary. Additionally, this device can also be used for over-temperature protection for core, controller, or power supply levels.

The DS1707EUA+T&R is a very versatile device that enables designers to monitor both power and temperature levels. With its wide operating temperature range, accurate power-on and power-off voltages, and user programmability, the DS1707EUA+T&R is ideal for a wide range of battery scalability, overvoltage or short circuit detection, and power management applications. This makes it an effective and cost-effective solution for designers looking to improve system reliability and reduce costs.
