The LM80CIMTX-5/NOPB is a power management integrated circuit (PMIC) developed by Texas Instruments, providing necessary functions and features for thermal management. It is designed to enable efficient and reliable system-level thermal management and is ideal for embedded and mobile applications.

The LM80CIMTX-5/NOPB is a thermal monitoring device and, consequently, features the fundamentally important functions of temperature measurement and temperature control. Specifically, this device combines temperature sensing and thermal management functions for usage in portable and embedded systems, such as laptop computers, notebook PCs, and cellular phones. The thermal management is implemented via two digital/linear outputs, two analog output pins, a pulse width modulation (PWM) output pin, and an I2C (Inter-Integrated Circuit) serial bus interface.

The device consists of a temperature sensor and an on-chip thermal management control circuitry in a single package. The temperature sensor enables the LM80CIMTX-5/NOPB to measure the temperature with a resolution of 8-16 bit, depending on the temperature range. The thermal management functions are better defined by the thermal control pins. These pins include:Two digital/linear outputs, two open drain outputs, and an open drain output pin. These pins can be used to control power transistors, relays, or other output devices.

The digital/linear outputs are used for controlling thermal monitoring and power regulation. The two open drain outputs also provide additional control for thermal protection, allowing for different levels of thermal protection for different components in the system. The open drain output pin can be used to signal an interrupt signal when any of the other thermal protection thresholds have been met.

The LM80CIMTX-5/NOPB also features an I2C serial bus 8-bit interface to allow system-level thermal management. This interface allows the device to communicate with other devices in the system in order to maintain thermal management throughout the system. The I2C interface also allows users to setup thresholds and hysteresis temperatures to activate or deactivate the thermal protection.

The LM80CIMTX-5/NOPB also features a PWM output pin which can be used to power external fan devices or to adjust the system clock frequency in order to manage thermal conditions throughout the system. In addition, the device integrates a 16-bit delta-sigma ADC that enables the device to accurately measure the voltage and thermal conditions of each component in the system.

The LM80CIMTX-5/NOPB is a highly integrated device that enables efficient and reliable system-level thermal management. The device provides a wide range of features suitable for numerous applications, providing optimal system-level thermal protection and management. The combination of temperature sensing, temperature control, and I2C interface, make the LM80CIMTX-5/NOPB an ideal choice for different portable and embedded applications.
