Power management integrated circuit (PMIC) - Supervisors have become increasingly popular in embedded systems. This is thanks to their ability to control the various power delivery components within a system. The LTC2915HTS8-1#TRPBF is an example of a supervisor that supports a wide variety of applications. This article will provide an overview of its application field, as well as its working principle.

Application field

The LTC2915HTS8-1#TRPBF is designed for battery-powered systems. It supports input/output voltages from 1.2V to 5.5V, and its operating temperature range is -40°C to ±125°C. Thanks to its low power consumption of only 125μA, this supervisor is well suited for applications that require low power consumption. It is also suitable for applications where power supply monitoring is necessary, as it can monitor both over-voltage and under-voltage conditions.

In terms of supported peripherals, the LTC2915HTS8-1#TRPBF supports up to 10 power toning pins. Each pin supports up to 2A of current, making it suitable for small to medium scale applications. It also supports programmable over-current protection, power-on reset, and watchdog timer functionality. This combination of features makes this supervisor suitable for applications in many different systems.

Working Principle

The LTC2915HTS8-1#TRPBF operates according to the power supervision principle. It senses voltage, current and temperature levels across the peripheral and takes necessary actions according to set thresholds. When input/output voltages reach their corresponding threshold, the supervisor will either generate a reset signal or turn off the power supply depending on the configuration.

The supervisor also provides programmable over-current protection and programmable power-on reset functionality. When the supervisor detects an over-current or under-voltage condition via its corresponding toning pin, it will issue an interrupt signal to the host to take corrective action. Lastly, the watchdog timer functionality can be used to detect system reset events as well as to reset the system if necessary.

Conclusion

In conclusion, the LTC2915HTS8-1#TRPBF is a highly capable supervisor with an impressive range of features and capabilities. It is suitable for applications in a variety of different systems, such as battery-powered systems, and its power consumption is especially low for its level of performance. Its combination of features, such as over-current protection, power-on reset and watchdog timer make this supervisor a great choice for embedded systems.
