With the development of modern electronics, power management integrated circuit (PMIC) plays an important role in the industrial field. PMIC equips with a variety of integrated power protection components, that reduce the design effort of related applications. It also supports flexible configurations of system power-on, power reset and reset monitoring functions. The LTC2913IMS-2#PBF can be categorized into PMIC - Supervisors and receives a great demand in the industrial field due to its advantages.

Introduction to the LTC2913IMS-2#PBF

The LTC2913IMS-2#PBF is a high-performance single-supply supervisor and power-on reset circuit. With the built-in independent 1.225V and 4.5V power rail sense circuit, it can monitor the status of power supply. It also detects voltage changes and indicates the correct power-on state without requiring a separate bias supply or Zener diode. The internal circuit is capable of handling supply voltages as high as 20V, and also features a fast response time, low quiescent current and long propagation delay.

The all-in-one solution of the LTC2913IMS-2#PBF makes it much easier for designers to add power protection in the organization. Its voltage monitor (VMON) can detect any drops from 1.65V to 6V and switch off the output to ensure safe operation. Moreover, the LTC2913IMS-2#PBF features a power-on reset circuit (POR) that can also monitor the overvoltage between 3V and 20V and provide a time-delay output. It also supports hot insertion and current limit, making it a great choice for industrial applications.

Working Principle of the LTC2913IMS-2#PBF

The LTC2913IMS-2#PBF contains two main components: a voltage monitor circuit and a power-on reset circuit. The voltage monitor circuit detects any supply voltage drops in the system and then switches the output off to prevent further damage. Furthermore, the voltage monitor provides an accurate status indication of the supply voltages, which can be used to monitor the power supply to ensure safe operation of the system.

The LTC2913IMS-2#PBF also features a power-on reset circuit, which can recognize a falling voltage on the power rail and generate a time-delay output for system startup. The power-on reset circuit also features hot insertion capability, which keeps the system active during power supply replacement. Additionally, the current limit feature provides protection from over-current conditions, keeping the device from being damaged from short-circuits.

Application Field of the LTC2913IMS-2#PBF

Due to its wide range of features, the LTC2913IMS-2#PBF has a wide range of applications. It can be used in automotive systems, industrial systems, consumer electronics, networking and telecommunications, and many other industrial and consumer applications. In the automotive industry, it can be used to monitor car battery voltage and provide a time-delay output to ensure the system is in a safe state before startup. Additionally, it can be used as an overvoltage protection device for consumer electronics.

In industrial applications, the LTC2913IMS-2#PBF can be used to monitor AC power supplies and protect against overvoltages. It can be used to protect electronic equipment from being damaged by high voltage spikes. Furthermore, the device can be used in industrial control systems, where it can be used to protect programmable logic controllers from unexpected power spikes. Additionally, the device can be used in consumer applications, where it can protect any electronic product from overvoltage conditions.

Conclusion

The LTC2913IMS-2#PBF is a powerful single-supply supervisor and power-on reset circuit. It can detect any drops from 1.65V to 6V in the system and switch off the output to protect equipment from damage. Furthermore, it can monitor AC power supplies and protect against overvoltages. The device also features a hot insertion capability, which is beneficial in situations where the power supply needs to be replaced. It is well suited for applications in the automotive, industrial, consumer electronics and communications industries.
