Introduction

The LTC2906CDDB#TRMPBF is a highly integrated power monitoring and supervisor IC offering up to three independent monitoring and/or fault protection functions. It is competitively priced, versatile and suitable for a wide range of consumer and industrial applications. This application note provides an overview of the LTC2906CDDB#TRMPBF, its application fields and its working principle.

PMIC - Supervisors Overview

PMIC – Supervisors are a type of device that is responsible for the supervision, protection and monitoring of the power supply and other electronic applications. These devices are commonly used in consumer, industrial and automotive applications to ensure the safety of the system and to prolong the system lifetime.PMIC - Supervisors have several features including:1. Voltage monitoring: Many PMICs have the ability to monitor a system’s voltage. This feature can provide critical notifications for a system in the case of unexpected voltage changes, allowing for corrective actions to be taken. 2. Over-current protection: Another important feature of PMIC-Supervisors is the ability to monitor current draw. By monitoring the current draw of the system, it is possible to take pre-emptive actions to prevent system damage caused by overloading or short circuiting. 3. Thermal monitoring: Thermal management is also an important factor in electronic system design. PMIC-Supervisors are capable of monitoring the thermal performance of a system in order to prevent overheating and reduce the risk of damage. The LTC2906CDDB#TRMPBF provides all of these features and more in a low-cost, highly integrated package. It is specially designed for use in consumer and industrial applications and delivers outstanding protection, supervision, and monitoring capabilities in a wide range of conditions.

LTC2906CDDB#TRMPBF Overview

The LTC2906CDDB#TRMPBF is a Fully Integrated Power Monitoring and Supervisor device from Linear Technology. This device offers 3 monitoring and/or fault protection functions, as well as an adjustable or manually settable power-on reset delay and an integrated voltage reference. The device is packaged in a 5-Lead SOT23 and is designed for use in industrial and consumer applications.The LTC2906CDDB#TRMPBF has an extremely versatile input range, ranging from 2.3V to 14V. The device also features a voltage reference ranging from 0.55V to 0.95V, allowing for more accuracy in monitoring and protection applications. The input-to-output delay time can be set between 200μs and 800μs, allowing for precise control of the reset timing in a variety of applications.

LTC2906CDDB#TRMPBF Applications and Working Principle

The LTC2906CDDB#TRMPBF is ideally suited for a wide range of consumer and industrial applications where monitoring and protection are needed ranging from small battery powered devices such as cell phones, cameras, and portable music players, to larger industrial and automotive applications. In a typical application, the LTC2906CDDB#TRMPBF can be interfaced with a power management IC to ensure against unexpected system failure or shutdown. By monitoring voltages, currents, and temperatures, the system can take pre-emptive actions to protect the system from damage caused by fault events. The LTC2906CDDB#TRMPBF will monitor the system and take action by either generating a reset signal or asserting a logic signal when needed. The reset signal can be used to reset the power management IC or other components to ensure that the system will restart properly after a fault event. The logic signal, on the other hand, can be used as a fault indicator, alerting the user of the fault before damage occurs. The LTC2906CDDB#TRMPBF is specifically designed to provide power monitoring, protection and reset functionality, with its three independent monitoring functions offering improved system safety and reliability.

Conclusion

The LTC2906CDDB#TRMPBF is a highly integrated PMIC - Supervisors offering up to three independent monitoring and/or fault protection functions. It is specifically designed for use in consumer and industrial applications and delivers outstanding protection, supervision, and monitoring capabilities in a wide range of applications. The device can provide a reset signal or an active logic signal and is competitively priced, making it a great solution for many industrial and consumer applications.
