DS1813-10/T&R

The DS1813-10/T&R is a monolithic device produced by Maxim Integrated Products that serves as an electronic switch and voltage supervisor. It provides an adjustable trip-point voltage supervisor circuit and two independent, low resistance, electronic switches. It is intended to provide protection against current overloads, unexpected input voltage transients, reversed supply polarities, and short circuits in three-terminal voltage regulators and other specialized power-supply systems. By combining several power components into one package, the DS1813-10/T&R affords greater system reliability, fewer components and fewer connections.

The DS1813-10/T&R offers several important features that make it well suited for a variety of applications. Its adjustable trip-point voltage supervisor circuit provides an accurate, adjustable switching threshold, which is adjustable by a single external resistor. Its current limiting feature protects load circuits from high currents due to unexpected voltage transients. The DS1813-10/T&R also incorporates low-resistance switches that can be used to drive devices such as voltage regulators, power transistors, solenoids, and relays. In addition, it provides an open-collector output for system reset or power-fail indication.

When used as an application-specific voltage supervisor, the DS1813-10/T&R is designed to be connected between a voltage regulator and a load. When the input voltage reaches a specified threshold, the device trips, opening an internal switch to isolate the load from its power source. When the input voltage drops to a pre-set voltage, the device re-sets and closes the internal switch, reconnecting the load to its power source. This process helps to protect the load from excessive voltage variations and provides a reliable reset to the load circuit.

The DS1813-10/T&R can also be used as an electronic switch. In this application, the device connects, rather than isolates, a load to its power source. When the input voltage reaches a specified threshold, the device closes an internal switch connecting the load to its power source. When the input voltage drops to a pre-set voltage, the device opens the internal switch, disconnecting the load from its power source. This application provides protection for sensitive devices such as data storage or telecommunications systems.

The DS1813-10/T&R is a versatile PMIC with a wide range of applications. Its adjustable trip-point voltage supervisor circuit and low-resistance switches make it an excellent choice for protecting sensitive electronics from power surges and voltage fluctuations. Its open-collector output also allows for integration with other systems for system reset or power-fail indication. Its performance and flexibility make it the perfect choice for use in three-terminal voltage regulators and specialized power-supply systems.
