The DS1816R-5-U+W is a low-voltage, high-performance supervisor circuit device, designed for price-sensitive applications that require long battery life, low power consumption and low component count. Its power dissipation approach helps to minimize the risk of component damage due to high current loads or voltage spikes.The DS1816R-5-U+W can be used in a wide range of applications, including automotive, industrial and consumer applications. In automotive applications, the device can be used to monitor engine speed, oil pressure, transmission position and other critical elements of the vehicle. In industrial applications, the supervisor can monitor temperature, pressure and other environmental conditions. In consumer applications, it can be used to monitor power supplies and other critical components.The main features of the DS1816R-5-U+W are its small size, high efficiency operating voltage range of 1.8V to 5.5V, low power consumption, and an adjustable output delay time of up to 10ms. It also has a manual reset input with an active low reset output signal and push-pull CMOS capabilities. It is available in a 2.4mm x 1.0mm form factor package.The DS1816R-5-U+W is designed with a built-in watchdog timer that detects Power-On Reset (POR) failures or system reset failures, as well as monitoring the input voltage levels in order to detect any power supply anomalies. The watchdog timer is preset to the maximum delay time of 10 ms and supports a manual reset pulse for resetting the device. Furthermore, the device has a wide operating temperature range of -40˚C to +85˚C and comes with a low leakage current of 0.01μA.The working principle of the DS1816R-5-U+W revolves around its built-in Voltage Supervisor circuit. When the input voltage falls below the preset trip point, the device will assert a reset signal and enable the power-on reset functionality. Additionally, the device provides an adjustable reset delay time and manual reset pulse, which can be used to detect power supply anomalies. The device also provides a push-pull reset output signal and input logic thresholds of 1.2V and 0.8V. The DS1816R-5-U+W is a simple, cost-effective and reliable supervisor circuit suitable for price-sensitive applications that require long battery life, low power consumption and low component count. Its adjustable reset delay, low power consumption and wide operating temperature range make it ideal for industrial, automotive and consumer applications, providing reliable power system monitoring for critical components.
