The L6716 is an integrated circuit that is commonly used in microprocessors and other designs which require a minimum of power or dynamic dissipated (or a combination of both) in order to achieve a suitable operating temperature requirement. The L6716 is part of the PMIC (Power Management ICs) family and is specifically classed as a ‘special purpose’ voltage regulator.

The L6716 performs two distinct functions. Firstly, it is a voltage regulator, meaning that it reduces variable voltages to a steady predefined voltage. This output voltage will vary, depending on the device being used, but typically the range can be between 1.5 and 13 volts with an accuracy of +/- 0.01%.

The second function of the L6716 is to provide temperature regulation. It does this by using an internal NTC thermistor which is used to control the output voltage in response to environmental temperature changes. It has the ability to sense temperature changes up to +85°C with an accuracy of +/- 3°C.

Moreover, L6716 has a voltage feedback loop error detection to provide system level protection if the output voltage is outside a specified range. In addition to temperature regulation, the device includes software-controlled shutdown mode which can be enabled via an I2C compatible interface.

The primary application of L6716 is in the field of microprocessor or other digital devices requiring dynamic power control or a minimum power dissipation. It is commonly used in PC mainboards, mobile devices, and other embedded systems where current or voltage must be regulated in order to protect components from excess or insufficient cooling.

The working principle of L6716 is simple. It operates as a linear voltage regulator, meaning that the input voltage is applied to the device in order to generate a regulated output. The device contains an NTC thermistor which is positioned within the temperature feedback loop. This thermistor provides temperature data to the internal circuitry of the device in order to regulate the output voltage in response to the temperature changes. When the temperature rises above a certain level, the device will adjust the output voltage accordingly in order to maintain a desirable operational range. Additionally, the device has an adjustable voltage reference which can be used to fine tune the output voltage to meet the application’s specific requirements.

The L6716 is a versatile and flexible voltage regulator which is often used to provide dynamic power control and temperature regulation in a variety of different systems. It is fast, easy to use, and reliable, making it an ideal choice for designers looking for a cost-effective solution for their voltage regulation needs.
