PMIC - Supervisors: LTC2966HSW#PBF Application Field and Working Principle

A type of integrated circuit referred to as a PMIC, or Power Management IC, is used to regulate, monitor and perform a wide range of power management functions. One of these is the LTC2966HSW#PBF Supervisors, which uses a variety of power-management features and benefits to provide ideal performance in a broad array of applications, while staying cost-effective.

Application Field

The LTC2966HSW#PBF are designed specifically for space-constrained, low-power applications, such as those in battery-powered electronics. These applications require efficient power management and optimal graphics performance, with minimal voltage droop. Because the LTC2966HSW#PBF can effectively deliver low-noise voltages, it is often used for high-precision voltage control and power supply monitoring. It also meets the latest low-voltage specifications and can be used for power supply protection in Class D audio amplifiers, PDAs, and smartphones.

Working Principle

The LTC2966HSW#PBF is comprised of a low-power supervisor controller and a low-noise voltage regulator, which make up the core of the power management solution. The supervisor controller keeps track of input-power characteristics and communicates to the system what type of power is being used. It also monitors a variety of conditions, including: input power, over-voltage, under-voltage, temperature, short-circuit protection, and fault detection. When any of these conditions are detected, the LTC2966HSW#PBF responds by controlling on/off circuitry and setting signals to regulate the power supply.

The low-noise voltage regulator operates by setting two outputs for each Load Power Domain (LPD). Each output is adjustable from 0.6 V to 5.5 V and 8 A of current can be controlled over the full voltage range. This feature allows the LTC2966HSW#PBF to perform true Load Power Domain (LPD) distributed power management. By accurately monitoring the input current, the LTC2966HSW#PBF can adjust the voltage outputs to maintain a steady overall DC output.

The LTC2966HSW#PBF uses a variety of protection features, such as over-current protection and over-temperature protection, to ensure safe and reliable operation. These protection circuits monitor all power controls, including input power, output power, and load current. All of these protection features are designed with an eye towards improved force tolerance, which ensures that the LTC2966HSW#PBF can accurately monitor and respond to a wide variety of conditions in real-time.

Conclusion

The LTC2966HSW#PBF is a highly versatile power management IC. Its combination of low-power supervisor controller and low-noise voltage regulator makes it ideal for space-constrained, low-power applications. It is capable of accurately regulating the input and output voltage, while offering over-current, short-circuit, over-voltage, and over-temperature protection features.

The LTC2966HSW#PBF is an excellent choice for power management applications and is increasingly being used in Class D audio amplifiers, PDAs, and smartphones.
