Power Management Integrated Circuits (PMICs) are one of the most widely used components in the electronics industry. PMICs are specialized integrated circuits that combine common power supply, control, and power monitoring circuitry. Supervisors, also known as voltage monitors, are one of the most common PMICs used in electronic systems. The LTC2903IS6-B1#TRPBF integrated circuit is a popular supervisor used for a variety of applications. This article will discuss the application field and working principle of the supervisor.

Application Field

The LTC2903IS6-B1#TRPBF is an analog supervisor IC offered in leaded and leadless packages. It is commonly used in PC motherboards and portable device applications such as notebooks, servers, and cell phone batteries. The supervisor IC provides overvoltage protection, overcurrent protection, brown-out detection, and power-on reset. It supports standard inputs such as +3.3V and +5V, as well as inputs up to 36V, making it suitable for a wide variety of applications.

The supervisor IC is also widely used in automotive applications such as airbags, power windows, and ignition systems. Its high-voltage capability makes it suitable for 12V automotive systems. Additionally, it can be used to support 12V applications with up to 36V input, making it suitable for automotive infotainment and navigation systems.

Working Principle

The LTC2903IS6-B1#TRPBF supervisor IC uses a hysteretical comparator type architecture to detect voltage levels and trigger a reset signal when the input voltage deviates from its programmed threshold. When the input voltage exceeds the upper threshold, a reset signal is sent to the system. When the input voltage drops below the lower threshold, a reset signal is also sent. This is done to maintain power for the system if the voltage supply drops below a certain level.

The supervisor IC also has an adjustable timeout period, allowing the user to set how long it will take for the reset signal to be triggered when the input voltage drops below the lower voltage threshold. Additionally, the reset signal output can be polarity-inverted to provide active-low or active-high reset signals, depending on the user’s system requirements.

The LTC2903IS6-B1#TRPBF supervisor IC also has an internal temperature sensor, which allows it to detect if the internal temperature rises to a critical level and trigger a reset signal. This is useful in applications where the system may be exposed to high temperatures, such as server racks or automotive applications.

Additionally, the IC has an adjustable watchdog timer, which can be used to monitor for a loss of communication or a malfunction in the system. If the system does not respond within a user-defined period, the supervisor IC can trigger a reset signal to reset the system.

The LTC2903IS6-B1#TRPBF supervisor IC is a versatile integrated circuit that is used in a wide variety of applications. Its wide input voltage range and adjustable timeout period make it suitable for use in consumer and industrial applications. Its power-on reset and temperature monitoring capabilities make it suitable for use in automotive applications. The supervisor IC can provide reliable overvoltage protection, overcurrent protection, and low-voltage monitoring, making it a valuable component in any electronic system.
