The DS17485S-3+ is a Real Time Clock (RTC) which is used in many applications to maintain time. It is intended to be used in low-power applications, operating with a low voltage power supply and utilizing standard battery backup. The unit can be used as a stand-alone RTC, or it can be interfaced to other systems for time synchronization. The DS17485S-3+ offers accuracy of ±2 minutes per month over its operating temperature range of 0°C to 70°C.
The clock is powered by two AA batteries, which provide power for up to two months when the main voltage supply is dual. This provides a backup in case the main voltage supply fails or is disconnected. The DS17485S-3+ contains features such as a crystal, a 32-bit timer, a watchdog timer, and a trickle charger for recharging the battery. It also has several output functions, such as an alarm, a power fail signal, and open-drain control outputs.
The DS17485S-3+ has an internal crystal that helps maintain accurate timekeeping. A 32-bit timer is also present, and it can be used to generate periodic interrupts or to enable time-sensitive events. A watchdog timer is present and can be used to automatically reset the system if it is not functioning properly. The trickle charger can be used to recharge the backup battery if the main voltage supply is not available.
The unit contains a real-time clock (RTC) that is used to maintain time. This clock can be adjusted in four-second intervals and can track days, weeks, and months. The RTC can also be used to enable alarms on a regular basis. The unit also contains an alarm output, which can be used to trigger events at specific times or on specific dates. Additionally, a power fail signal is available, which gives an early warning of a power interrupt or brownout.
The DS17485S-3+ is suitable for applications where high accuracy and reliability are required. It can be used to control time-sensitive events, such as data logging, synchronizing clocks, and alarm functions. It is also suitable for applications that require backup power, such as medical systems, transportation systems, and security systems.
Overall, the DS17485S-3+ is an ideal choice for many applications that require accurate timekeeping and reliable backup power. It is a low-power unit that is accurate and reliable, offering a wide range of features for its size. The DS17485S-3+ provides a cost-effective way to implement Real Time Clock capability into a range of low-power, time-sensitive applications.
