PMIC - Supervisors: LTC1726EMS8-2.5#TRPBF Application Field and Working Principle

The LTC1726EMS8-2.5# TRPBF is an ultra-low power voltage supervisor family specifically designed for embedded systems applications. Manufactured by Linear Technology Corporation, this family of voltage supervisors includes several variants with various features that enable it to be suitable for different applications. This article explains the application field and working principle of the LTC1727EMS8-2.5# TRPBF.

Application Field

The LTC1727EMS8-2.5# TRPBF is suitable for use in different embedded systems applications such as motor control systems, hand-held devices, wireless communications and load sharing applications. Its wide input voltage range 2.0 V to 5.5 V and its very low supply voltage (1.6 V) are suitable for low voltage embedded systems.

The LTC1727EMS8-2.5# TRPBF is robust, tolerant to input voltage drops, and can work effectively in extreme temperatures (-40 °C to +85 °C). Its low current consumption of about 120-200 μA permits the voltage supervisor to operate without consuming current from the main supply, further decreasing its power consumption. Additionally, the LTC1727EMS8-2.5# TRPBF has an accuracy of 0.25%.

Working Principle

The LTC1727EMS8-2.5# TRPBF works according to the voltage supervisor principle. This means it keeps track of the input voltage and can be used to detect changes in the voltage and react accordingly. Its working principle is explained in the following steps.

1. The LTC1727EMS8-2.5# TRPBF is connected to the input voltage source.
2. It monitors the input voltage and, if the input voltage drops below or rises above a predetermined threshold, it produces an output signal.
3. This output signal is then processed by the controlling system and depending on the output produced, the controlling system can take appropriate action.

The LTC1727EMS8-2.5# TRPBF is also equipped with open-drain output and an active-low RESET/NMI/PFI output that can be used to drive an external reset circuit, an interrupt line, or an interrupt controller.

Conclusion

The LTC1727EMS8-2.5# TRPBF is a low power voltage supervisor suitable for use in embedded systems applications. It works according to the voltage supervisor principle and is equipped with an active-low RESET/NMI/PFI output for controlling external circuits, interrupts and interrupt controllers. Its wide input voltage range and low current consumption make it an efficient device for embedded systems applications.
