TPL5100DGSR is a programmable timer and oscillator from Texas Instruments. It provides a wide range of applications and working principles, including time keeping, programmable battery life extension, and acoustic management.

Application Field

The TPL5100DGSR is suitable for a wide range of applications, including: industrial applications, smart home and service applications, automotive applications, metering and monitoring applications, as well as gaming applications.

It is designed for long time-keeping operation using precise time intervals with extremely low power consumption of 1.2uA. It provides autonomous control of functions through precise timing and low power operation, while providing a programmable timer and oscillator capable of reducing space and power.

It includes a wakeup and load powerdown system, allowing users to store wakeup, alarm and shutdown settings. This system helps to extend the life of the battery and provides a cost-effective option compared to other programmable timers and oscillators.

The device also includes a nonvolatile configuration EEPROM with temperature compensation, high accuracy, and low operating temperature drift. Temperature compensation allows the timer and oscillator to still operate accurately even when exposed to extreme temperatures, such as those in automotive and industrial applications.

The device also features a low noise output and adjustable slew rate for improved acoustic performance. This can help to reduce annoying audible artifacts in applications such as noise-sensitive gaming, when paired with the appropriate software.

Working Principle

The working principle of the TPL5100DGSR is based on the combination of a programmable timer and an oscillator circuit. The programmable timer is responsible for timing intervals, while the oscillator allows users to precisely set and adjust the clock frequency. The result is a programmable timer and oscillator that offers precise timing accuracy and a low power consumption of only 1.2uA.

The timer is configured by setting the various wakeup/alarm/shutdown parameters in the device’s EEPROM. This allows the device to autonomously control various functions based on the timer and oscillator settings. The device also includes a low-noise output and adjustable slew rate for improved acoustic performance.

The TPL5100DGSR also features a temperature compensation circuit for improved accuracy in extreme temperatures such as those found in automotive and industrial applications. This is achieved by using a combination of resistors and capacitors to provide the temperature compensation, which is adjustable with the EEPROM.

In addition, the device includes a wakeup/load powerdown system. This system allows users to store the various wakeup/alarm/shutdown settings once, and then the device will autonomously control these settings based on the timer and oscillator settings.

Overall, the TPL5100DGSR offers a wide range of applications that require precise timing and low power consumption in a single chip solution. By combining a programmable timer and an oscillator, the device offers a cost-effective alternative to other programmable timers and oscillators with extremely low power consumption.
