PMIC - Supervisors

PMIC (Power Management Integrated Circuits) supervisors are commonly used in most modern electronics applications. These devices act as a “guardian” when it comes to power-up, power-down and power-on reset - all of which are crucial in ensuring the proper operation of electronic components of an integrated circuit. LTC2911CTS8-3#TRPBF is one of the most popular PMIC supervisors on the market. This article will explain its application fields and working principle.

Application fields:

The primary application of the LTC2911CTS8-3#TRPBF is as a power supervisor in digital systems. This powerful PMIC has both active and inactive modes, and is ideal for setting up an various functions such as power sequencing, tracking, monitoring, under-voltage and over-voltage protection, and reset specifications. It is similar to other PMIC supervisors in that it provides a low-current, low-power solution for power sequencing, tracking, and reset protection.

The LTC2911CTS8-3#TRPBF is specifically designed for use in audio, video, and communication systems, as well as in various industrial process control applications. It is used extensively in logic systems and in other microprocessor-based electronics that require microprocessor resetting and power supply sequencing. This device also has extensive industrial use and is included in extremely sensitive process control systems.

Working principle:

The LTC2911CTS8-3#TRPBF is a high-performance power supervisor with an 8-bit microcontroller-based architecture. It is designed to provide powerful protection features and maintain the power integrity in digital systems. The device provides Power Good and Reset outputs, allowing it to be used as a supply voltage and microprocessor reset control element. It is also equipped with circuitry to detect under-voltage/over-voltage/over-current/short circuit conditions and maintain proper power sequencing.

At the heart of the LTC2911CTS8-3#TRPBF power management integrated circuit is a 5-channel analog-to-digital converter. This converter is used to monitor the supply voltages and temperature of the system. The ADC also produces an active low power-good signal, alerting the system of any deviations in the supply voltages. If any of the monitored conditions are no longer within their specified range, the Power Good signal will be activated, alerting the system to an impending fault condition.

The Reset output of the device generates an active-high reset signal. The reset signal is generated when the internal voltage of the device is below the set limit. This reset signal is used to reset the microprocessor, indicating a condition where the system is not operating normally. This reset signal is also used to activate power-down and power-up reset circuits.

Conclusion:

The LTC2911CTS8-3#TRPBF is an excellent choice for power management and microprocessor reset protection circuits. With an 8-bit microcontroller-based architecture and an integrated 5-channel analog-to-digital converter, this device is ideal for use in complex and sensitive electrical systems. Furthermore, the device’s Power Good and Reset outputs enable it to be used as a supply voltage and microprocessor reset control element.
