Package / Case
Package / Case refers to the physical housing or enclosure that encapsulates an electronic component. It provides protection, facilitates handling, and enables electrical connections. The package type determines the component's size, shape, pin configuration, and mounting options. Common package types include DIP (dual in-line package), SOIC (small outline integrated circuit), and BGA (ball grid array). The package also influences the component's thermal and electrical performance.
MSOP
Number of Pins
Number of Pins: Indicates the number of electrical connections available on the component. These pins are used to connect the component to other components or circuits on a printed circuit board (PCB). The number of pins determines the functionality and connectivity options of the component. It is important to ensure that the component has the correct number of pins for the intended application.

Reset
Reset is an electronic component parameter that refers to the process of returning a device or system to its initial state. This can be done by applying a specific voltage or signal to the device, or by physically resetting the device. Resetting a device can be used to clear errors, restore default settings, or to start the device over from the beginning.

Description
The LTC1726 is a triple supply monitor and microprocessor supervisory circuit with adjustable reset and watchdog functions. It is designed for systems with multiple supply voltages and features a common open-drain reset output with an adjustable delay. The reset and watchdog timeout periods are both adjustable using external capacitors. The LTC1726 has tight 1.5% accuracy specifications and glitch immunity, ensuring reliable reset operation without false triggering. The RST output is guaranteed to be in the correct state for Vccs/Vcc25 or Vcc3 down to 1V. The LTC1726 can also be configured to monitor any one or two Vcc inputs instead of three, depending on system requirements. Its low (16µA typical) supply current makes it ideal for power-conscious systems.
Features
