BQ4802YPWR clocks are advanced real-time clocks (RTCs) used for time tracking and event scheduling in embedded systems. They are based on a low-cost, low-power architecture and can be used in a wide range of applications. The BQ4802YPWR is a simple, yet powerful RTC designed to be used in a variety of different applications such as handheld devices, video surveillance systems, and augmented reality (AR) applications.

The BQ4802YPWR RTC includes an integrated quartz crystal oscillator, a temperature compensated oscillator (TCXO), and a P-MOS transistor for the power supply switch. The oscillator has a frequency stability of ±3ppm over its temperature operating range. This ensures that the timekeeping accuracy of the BQ4802YPWR is highly accurate and reliable. Additionally, the BQ4802YPWR also provides an internal temperature sensor for temperature monitoring and can be used for temperature compensation in applications such as mobile phone battery monitoring.

The BQ4802YPWR provides a variety of features to support event scheduling and timekeeping. The clock has a built-in calendar function, which supports up to 12 months of time keeping, as well as a 24-hour alarm mode that can be scheduled for certain days of the week. Additionally, the BQ4802YPWR also features a temperature sensor and adjustable power saving sleep mode. This helps reduce power consumption while the clock is in use.

The BQ4802YPWR also includes an external power supply input with a voltage range of 1.2V to 3.3V. This allows the clock to be powered from an external power source, such as a battery, or from an AC adapter. The device also has an embedded watchdog timer for fail-safe timekeeping, which can be enabled to reset the system if necessary. Additionally, the BQ4802YPWR is also equipped with an LED indicator and a signal output pin, allowing it to be easily integrated into existing hardware.

BQ4802YPWR clocks are ideal for applications that require precise timekeeping and event scheduling such as embedded systems, handheld devices, video surveillance systems, and AR applications. Their small size, low power consumption and accurate timekeeping make them a great choice for time tracking and event scheduling.
