The W83L771ASG TR is a type of power management integrated circuit (PMIC) developed by a company called TiWi, and it is often grouped broadly into the field of thermal management. It is a 3.3V input voltage, 8 pin, low power BiCMOS device featuring protection and management functions specifically designed to improve the thermal performance of surface mount devices within applications requiring superior overload and blink protection characteristics. The powerful management features, combined with its highly efficient design, make the W83L771ASG TR an ideal choice for temperature control applications.

The W83L771ASG TR is designed to significantly reduce the power dissipation generated by either an LED or microprocessor while still providing superior temperature control performance. It utilizes a current source with a preset current set by the user, and then uses the current source to directly monitor and control the temperature. Through the current source and thermally-sensitive resistors, the device is able to detect the ambient temperature of the environment and then adjust its output current accordingly. The device features a low level shutdown input, where the voltage on the input can be adjusted between 0-5V, allowing for maximum control of temperature at different temperature ranges.

The W83L771ASG TR also includes low power consumption, a low output voltage ripple, and a low output voltage tolerance. These features make the device ideal for tight thermal environments where power must be conserved. In order to achieve the robust temperature control functionality, the device includes a wide range of protection features including over temperature protection and overload protection. In addition, the device can also be used in applications requiring blink protection, allowing a controlled blink rate to reduce heat accumulation on the targeted device.
