The DS1816-5+T&R supervisory circuit from Maxim Integrated is a multi-purpose circuit designed for monitoring various operating conditions. This supervisory circuit functions as a watchdog timer, undervoltage detector (UV) and reset controller to ensure reliable system power-up and power-down operation. It provides three independent reset signals and two watchdog outputs, making it a perfect choice for supervisor applications in harsh environments.

DS1816-5+T&R offers a number of advantages over traditional supervisor circuits. It features an adjustable power-on/power-off reset delay, so that system boot-up can be delayed until all supplies have stabilized. It also offers an adjustable watchdog timer interval that facilitates an interval reset to activate software methods for system recovery. The dual watchdog timer functions can be used for time-stamping system events and to ensure that critical communications are still functioning.

The DS1816-5+T&R is ideally suited for applications in automotive, medical and military equipment, as well as most microcontrollers. It can be used to provide reset and watchdog functions that severely reduce system malfunctions and improve system reliability. Thanks to itsfeatures and components, the DS1816-5+T&R can provide a robust system design that can withstand harsh operating conditions.

In terms of working principle, the DS1816-5+T&R continuously monitors the power supply inputs to ensure the voltages remain within an acceptable range. If an input voltage drops below a preset threshold, the circuit will assert reset and a watchdog signal. This signal can be used by the system to recover from an error or other operating conditions. The dual watchdog timer outputs can also be used to time-stamp system events and to ensure that critical communications are still functioning.

All of the components in the DS1816-5+T&R are housed in a small 6-pin TSOT package, allowing it to fit comfortably into the most constrained of designs. It is also available in a wide range of operating temperatures, from -40°C to +85°C, making it an ideal choice for applications that require robust supervisory circuits.

The DS1816-5+T&R is a reliable, cost-effective setup for monitoring power supply voltages and providing reset and watchdog output. Its adjustable power-on/power-off reset delay and watchdog timer interval offer reliable system power-up/power-down sequence control, while its unique dual watchdog functions enable critical communication monitoring and system event time-stamping. Its small size and wide range of operating temperature makes it the perfect choice for supervisors in harsh operating environments.
