PMIC - Voltage Regulators - Special Purpose
The L5951 is a Popular High Voltage Fast Voltage Regulator Controlling Step Down Automotive Applications.
The voltage regulator controls the supply voltage for many systems in an automobile, which makes it an important component in the automotive industry. The L5951 is a particularly fast voltage regulator featuring a power-on reset and numerous active low protection modes. This makes it perfect for use in automotive applications, such as automotive lights, horns, and HVAC.
Application Field
The L5951 is primarily used in automotive applications, as it has the fast switching characteristic required. It is usually used to control the voltage of systems in an automobile, such as the headlights, horns, or HVAC. It is also suitable for other applications where fast voltage control is required, such as engine control systems, industrial equipment, and other products which involve fast switching power circuits.
Working Principle
The L5951 works by using an internal voltage reference connected to an output voltage sensing circuit. When the output voltage goes above the reference, the circuit will reduce the output down to the reference voltage. The voltage reference is adjustable so that the circuit can be tailored for specific applications.
The L5951 also features power-on reset and numerous active low protection modes. When power is first applied to the voltage regulator, the power-on reset feature will ensure that the output is kept below an acceptable level until the circuit is initialized with the correct control settings. The protection mode will activate if the output is too high and cut power when necessary in order to protect the system.
The L5951 is a fast and reliable voltage regulator with several important safety features which make it ideal for automotive use. Its fast switching and active low protection modes make it capable of controlling a wide range of automotive systems.
