LTC2903CSS6-B1 #TRM Application Field and Working PrinciplePower management integrated circuits (PMICs) are the core component of all electronic systems. They control the design of power circuits, manage power supply operations and maintain system stability. Among other strategies, PMICs ensure that the voltage remains within the specification range throughout the entire power cycle of the system.The LTC2903CSS6-B1 #TRM is a high-performance Supervisor and Voltage Monitor with power management and sequencing capability. It offers an integrated programmable voltage monitor, voltage monitoring thresholds with adjustable hysteresis and adjustable trim levels that deliver precise control of the supply line. Additionally, the ability to set alarms and asserts over a range of three adjustable thresholds make it an ideal choice in many different applications.LTC2903CSS6-B1 #TRM is ideal for a wide range of applications, from electronic point of sale (EPOS) systems to telecommunications systems and computer accessories. It is also suitable for use in applications where power supply optimization, resource management and system shutdown are required. The LTC2903CSS6-B1 # TRM can be deployed for a variety of power management tasks. It can be used to monitor and protect system components such as power related peripherals. It can also be used to detect faults and initiate corrective action like shutdown of the system when predetermined thresholds are exceeded. Additionally, it features an integrated programmable voltage monitor, voltage monitoring thresholds with adjustable hysteresis and adjustable trim levels.In terms of working principle, the LTC2903CSS6-B1 #TRM is an intelligent monitoring device that can detect whether the demand on the system is greater than the capacity of the power source. If the source voltage is too low, the Supervisor sends an alert to the microcontroller (MCU) in the form of an assert. If the source voltage is too high, the Supervisor sends an alert to the MCU in the form of an alarm. Also, the LTC2903CSS6-B1 #TRM can monitor the status of multiple power supply rails, providing reliable and precise control of system power management requirements. Additionally, it can detect when a supply voltage is going out of range and will alert the MCU in the form of an assert or alarm.In summary, the LTC2903CSS6-B1 #TRM is a high-performance Supervisor and Voltage Monitor with power management and sequencing capability. Suitable for a wide range of power management tasks, it is an ideal choice for applications where power supply optimization, resource management and system shutdown are required. Thanks to its integrated programmable voltage monitor, voltage monitoring thresholds with adjustable hysteresis and adjustable trim levels, LTC2903CSS6-B1 #TRM can accurately monitor the status of multiple power supply rails and initiate corrective measure when necessary.
