The S-8252ABO-I6T1U is developed by the Sharp Corporation and is a low dropout linear voltage regulator. This linear voltage regulator (LVR), with its flexibility and integrated features, is designed to be an efficient and reliable IC for any battery-cultivated product. It could be used in applications such as mobile phones, tablet PCs, portable game consoles, remote control toys, car toys and medical devices, etc. This article will discuss the applications of the S-8252ABO-I6T1U and its working principle.

Applications of S-8252ABO-I6T1U

The applications of S-8252ABO-I6T1U are divided into two different areas: power management and battery management. In terms of power management, the S-8252ABO-I6T1U supports a wide range of input voltages from 0.9 V to 6V and output voltages from 0.9V to 6V. It is capable of delivering currents up to 3A, which is powerful enough for many power management applications such as providing system power, driving DC motors, and charging Li-ion batteries.

As for battery management, the S-8252ABO-I6T1U is particularly applicable in managing single-cell lithium-ion batteries. This LVR is able to output a precise voltage (1.2V to 4.35V) even under the varying loads and temperature, which is essential in ensuring a stable and consistent battery performance. The S-8252ABO-I6T1U is also compatible with different types of rechargeable batteries such as Ni-MH, Ni-Cd, and Li-ion, allowing it to be used in various battery-Farming applications as well, such as powering up devices, assemblies, and electronic items.

Working Principle of S-8252ABO-I6T1U

The S-8252ABO-I6T1U uses a linear voltage regulator based on a linear power supply module. The LVR works by using the PNP type transistors and lower dropout voltage regulator (LDO) technology to ensure a stable voltage output. The LDO is made up of two transistors, a PNP transistor for the regulator and an NPN transistor for the output impedance.

The regulator present in the S-8252ABO-I6T1U consists of two main parts, the main power source and the output stage. The main power source, typically the battery, supplies electricity to the IC via an input capacitor. The input voltage is then regulated by the LDO module found inside the IC. The output stage is responsible for delivering the regulated voltage to the load. As the load current increases, the voltage would drop and the regulation process is achieved by the LDO. The voltage is regulated by adjusting the PNP transistor\'s base current, thus controlling the output voltage.

In addition, the S-8252ABO-I6T1U has built-in temperature protection, which shuts the LDO down in conditions that exceed the rated temperature range. This reduces the chances of IC failure due to exposure to a harsh environment. The S-8252ABO-I6T1U also has a built-in overcurrent protection mechanism, for protection against any sudden increase in current that could possibly damage the device or the system.

Conclusion

The S-8252ABO-I6T1U is a low-dropout linear voltage regulator developed by the Sharp Corporation. It supports a wide range of input and output voltages and is capable of delivering currents up to 3A. It is a reliable device suitable for power management and battery management applications such as providing system power, driving DC motors, charging Li-ion batteries, and powering up electronic items. The S-8252ABO-I6T1U uses an LDO to regulate the output voltage by adjusting the PNP transistor\'s base current. Apart from that, it also has temperature and overcurrent protection mechanisms built in for better stability and protection.
