TL7705BCDRE4 Application Field and Working Principle

The TL7705BCDRE4 is a tal crown IC from Texas Instruments that is categorised in its Power Management ICs (PMIC) range. This IC is specifically a Supervisors range IC and its main purpose is to provide supply monitoring and reset of a given system.

Function

The TL7705BCDRE4 monitors the Vcc supply of a given system and, when the value falls below one of the four programmable thresholds, it will initiate a low, override or power on reset. The reset delays can also be programmed, allowing for the system to be reset with a different delay based on the threshold value of the supply voltage.

In addition to the four programmable reset thresholds, the TL7705BCDRE4 also has two other thresholds, one being an adjustable reset active comparator and the other being a reset inactive comparator. This allows the system to be kept reset until the supply voltage reaches a certain level. Furthermore, the IC also has monitoring and detection circuitry to detect when the supply voltage is above the overvoltage threshold.

Features

The TL7705BCDRE4 has several features that makes it suitable for a variety of applications. Firstly, it boasts a wide input supply voltage range from 0.9V to 28V, which makes it suitable for use in many different systems. Furthermore, the IC has ultra-low power consumption of 1 microamp, making it ideal for use in battery-powered applications.

Another key feature is that the IC is highly configurable, allowing for the reset thresholds, reset delays and reset outputs to be easily programmed. This level of flexibility makes it suitable for a variety of applications. In addition, the IC has a high level of noise immunity, making it suitable for use in environments with high levels of EMI.

Applications

The TL7705BCDRE4 is ideal for use in embedded systems and microcontroller-based applications. It can be used to monitor the supply voltage of a system and initiate a reset when the voltage is below a given threshold. It is widely used in industrial and telecommunication applications where a reliable power supply is essential. It is also widely used in automotive applications, where the IC is used to detect when the battery voltage drops below a preset value.

The IC is also widely used in power distribution systems and power supplies, where it is used to detect when the voltage drops below a given threshold and initiate a reset. This ensures that the system is automatically reset in the event of a power outage or other such event.

Conclusion

The TL7705BCDRE4 is a power management IC from Texas Instruments that is categorised as a Supervisors IC. Its main purpose is to monitor the supply voltage of a given system and initiate a reset when the voltage drops below one of the four programmable thresholds. It has a wide input voltage range and ultra-low power consumption, making it suitable for use in a variety of applications. The IC is highly configurable, allowing for the reset thresholds, delays and outputs to be programmed easily. It is widely used in embedded systems, automotive applications and power distribution systems where a reliable power supply is required.
