The DS1816R-10-U+ is a popular single-supply reset IC that is used in power supply reset applications by providing a low reset voltage, a reset input polarity selection, and a reset output-hold delay. It functions as a power monitor and supervisor for digital systems, and is especially useful for system standby and reset circuits that need a fast-response reset. The device is available in a few different packages, such as the SuperSOT-6, the Ultra Thin-Sip, and the SOIC-8.
When the reset input threshold is exceeded, the DS1816R-10-U+ will reset the system by forcing a low voltage on an active-low RESET output, keeping the output low until it is reset. The reset time is adjustable with a resistor and capacitor placed between VDD and RESET, and the reset input polarity can be selected whether an active-high or an active-low signal is used. The DS1816R-10-U+ also features temperature-compensated circuitry and a built-in 10ms reset output hold delay.
The DS1816R-10-U+ is mainly used in systems that are powered from a single supply, such as printer power supplies, routers, wireless systems, and network systems. It is also a great choice for system supervisory and monitoring applications, as it provides the fast reset response that is needed. It is designed to operate from a single-supply voltage range of 2.25V to 5.5V and can withstand surges up to 2.1A.
The DS1816R-10-U+ has a low reset voltage of 350mV and a reset input threshold that is adjustable, providing a wide range of reset signal time delays. The device has an accurate threshold voltage of 0.5V and a -3dB bandwidth of 10KHz, allowing it to detect transient input signals. The DS1816R-10-U+ also features a low power consumption mode, which reduces the device current consumption when the external power supply is lower than the reset threshold voltage.
The DS1816R-10-U+ is particularly useful in situations where a system reset is needed quickly and accurately. The device is well-suited for system supervisory and reset applications, as well as for power supply reset applications. It is also a great choice for systems that need to be protected from over-voltage and over-current, as the device will provide a fast reset response that prevents system damage from happening. Additionally, the DS1816R-10-U+ is easy to use with its low voltage, adjustable reset input threshold and adjustable reset output hold delay.
The DS1816R-10-U+ is an ideal choice for single-supply operation applications, providing a low reset voltage, an adjustable reset input threshold, and adjustable reset output-hold delay. It is well-suited for system reset applications that need a fast-response and accurate reset, as well as for power supply reset applications. It is also great for protecting systems from over-voltage and over-current, as the device will provide a fast reset response that prevents system damage from occurring.
