Power management integrated circuits (PMICs) are essential semiconductor components that are used in almost all modern electronic systems. The Texas Instruments LTC2919IMS-3.3#TRPBF falls into the category of supervisors, providing integrated protection for a variety of system designs. The versatile chip provides overvoltage and undervoltage monitoring, as well as an integrated watchdog timer and precision supply voltage monitoring.

PMICs are used to manage power and protect the system from dangerous voltage levels. The LTC2919IMS-3.3#TRPBF has several integrated features specifically designed to protect against a wide array of voltage conditions. The chip incorporates overvoltage and undervoltage monitoring, as well as a watchdog timer and precision supply voltage monitoring. The chip also features a power on reset monitor, reset output, and reset timeout.

Application Field

The LTC2919IMS-3.3#TRPBF is a versatile chip with a wide range of applications, such as industrial, wireless, automotive, and medical equipment. The chip can be used to monitor various voltage levels and provide overvoltage and undervoltage protection. It can also be used as a watchdog timer for systems that require constant monitoring. It is well-suited for both stand-alone and embedded applications. It is also compatible with a variety of operating systems and microcontrollers. These features make the chip an ideal choice for many complex system designs.

Working principle

The LTC2919IMS-3.3#TRPBF provides a variety of overvoltage and undervoltage monitoring features. The chip is powered by 3.3V and uses a voltage reference to measure the voltage levels of the system. When the voltage level reaches either the overvoltage or undervoltage level, the chip will output a logic high signal and can be used to trigger the reset output. The chip also has an adjustable watchdog timer that triggers an output signal if a certain amount of time passes without a reset signal being received.

In addition to overvoltage and undervoltage monitoring, the chip also provides precision supply voltage monitoring. This feature allows the chip to monitor the voltage level of the system and output a logic high signal if the voltage is not within the set threshold. This is useful for system designs that require precise control over the power supply.

The chip also features a power on reset monitor, reset output, and reset timeout. The power on reset monitor is used to detect an abnormal system restart and initiate a reset. The reset output is a logic-high signal that can be used to reset the system when an overvoltage or undervoltage condition is detected. The reset timeout is a configurable timer that will cause a reset if a reset signal is not received within a set amount of time.

Overall, the LTC2919IMS-3.3#TRPBF is an ideal chip for a variety of system designs. Its integrated features provide efficient and reliable power management for systems that require overvoltage and undervoltage protection, precision voltage monitoring, as well as watchdog timer and power on reset monitoring capabilities.
