Introduction

Power Management Integrated Circuits (PMICs) are integrated circuits that manage the power components of an electronic system. Among the most common types of PMICs are Voltage Regulators, Regulators, Voltage Reference and Supervisors. Supervisors are an important type of PMICs that are used to monitor and control the power of a system. The LTC2912CDDB-2#TRMPBF is a microprocessor supervisory circuit that offers overvoltage, undervoltage, and over current protection. This article will discuss the application fields and working principle of this device.

Application Fields

The LTC2912CDDB-2#TRMPBF is designed to detect and protect circuits against fast changes in input voltages, undervoltage, overvoltage, and overcurrent conditions. It is suitable for a wide range of applications, including automotive, telecommunication, industrial, and consumer electronics. This device is widely used in industries to protect sensitive circuits from power supply fluctuations. It also provides software-controlled reset/power-on reset and is highly tolerant to noisy environments. The LTC2912CDDB-2#TRMPBF is highly appropriate for battery-operated systems where sudden changes in input voltages can cause system shutdown. It features an adjustable timeout period and a wide operating temperature range of –40°C to +85°C. This makes the device suitable for applications with extreme temperature conditions.

Working Principle

The LTC2912CDDB-2#TRMPBF is a voltage monitor and supervisor IC that operates as a Passive Electronic Component (PEC) in the system. It is designed to protect the system against high and low-voltage conditions. It is a single-supply microcomputer reset/power-on reset device that provides overvoltage, undervoltage, and over-current protection. The LTC2912CDDB-2#TRMPBF has an adjustable voltage threshold that enables it to detect a wide range of voltage levels. It has an external capacitor (not included) to accurately specify a timeout period. An inrush current limit feature is provided to protect the system from high current transients that can cause damage to the system. It also has an active logic output with an adjustable threshold. The device is housed in a small surface-mount package with an operating temperature range of –40°C to +85°C.

Conclusion

The LTC2912CDDB-2#TRMPBF is a useful device in power management applications. It provides overvoltage, undervoltage and overcurrent protection, suitable for sensitive circuits and extreme temperature conditions. It has an adjustable voltage threshold so that it can detect a wide range of voltage levels. The device also has an active logic output, reset/power-on reset and an additional inrush current limit feature. It is easy to use and requires minimal external components.
