The DS1819AX-20+T&R is a low power, precision voltage supervisor with windowed trip and reset. These supervisors provide high accuracy monitoring of voltage supply, which offers the user a solution engineered to monitor power system control. In addition to providing adequate control in power systems, they allow higher system efficiency, as they do not require expensive controllers. They are frequently used in applications requiring power supply monitoring, such as motor, industrial and automotive control systems.

At the core of the DS1819AX-20+T&R is a precision-regulating voltage detector that is capable of controlling voltage fluctuations within a predetermined range, thus providing stable system power supply. The detector is composed of comparators, reference generators and latch circuits, set in an IC package. The IC also includes a supply voltage indicating indicator (if the voltage drops outside the monitoring range). The reference threshold voltages and reset hysteresis can be defined through external resistors.

The DS1819AX-20+T&R has two functions, windowed trip and reset. Windowed trip alerts the user if the detected voltage exceeds an adjustable level. This could be a sign of an overload or defective power source. The reset function allows the user to reset the system when the correct supply voltages are reached. The reset delay time is adjustable between 10ms and 10s.

The DS1819AX-20+T&R also includes an active Supply-On-Delay (SOD) circuit, which delays the power supply until the voltage reaches a certain level. This has the functions of accurate indication to the circuit and improved system reliability. The overvoltage/undervoltage detector output can be controlled by the reset input pin or by the supply voltage indicator output.

The DS1819AX-20+T&R voltage supervisor can be used in many varied applications, such as motor control systems, industrial equipment and automotive controllers. It offers excellent protection against short circuits, overvoltage and undervoltage. It is also optimized for low power consumption and is compliant with the RoHS directive.

In summary, the DS1819AX-20+T&R is a low power, precision voltage supervisor with windowed trip and reset features. It is designed to monitor voltage supply, and can be used in motor control, industry and automotive systems. Its active Supply-On-Delay (SOD) circuit ensures accurate supply indication to the circuit and improved system reliability. The overvoltage/undervoltage detector output can be controlled by the reset input pin or by the supply voltage indicator output. The DS1819AX-20+T&R is RoHS compliant and is ideal for applications requiring power supply monitoring.
