S-8211AAB-M5T1G

PMIC - Battery Management

The S-8211AAB-M5T1G is a primary/secondary pixel regulator tracking driver with an integrated charge pump. It is a component of a Power Management Integrated Circuit (PMIC) series that has been specifically designed for Battery Management (BMS) applications. It is the ideal solution for powering large digital displays, LCDs and OLEDs, with extremely high power efficiency and low power consumption. It features a low quiescent current, low voltage drop across its MOSFETs and a high-precision internal RCV digital loop filter.

S-8211AAB-M5T1G has two inputs that can be used for primary or secondary pixel power supply. Its primary input is a battery or a regulated source, while the secondary input is a DC/DC converter output or an external source. It offers a number of advantages to the end system, including improved system efficiency, low output ripple and higher resolution images.

At its core, the S-8211AAB-M5T1G has a wide input voltage range from 6.6 V to 24V, along with a 3.3V internal regulated output for the LCD panel and a charge pump for the RGB panel. The device also features a patented jitter suppression that limits undesired noise and jitter, resulting in improved image quality. Additionally, the device provides an integrated low quiescent current, voltage-programmable Overcurrent Protection (OCP) and Thermal Protection (TP) circuits, enabling designers to protect both the device and their end design from thermal and overcurrent conditions.

In terms of its operation, the S-8211AAB-M5T1G uses a primary/secondary pixel regulator tracking driver to ensure a constant voltage level to the LCD panel, regardless of the input voltage level. The device is capable of tracking up to three Primary supplies and up to two Secondary supplies. This allows for maximum flexibility in allowing for either direct battery, regulated source or DC/DC converter power supplies to the panel.

The S-8211AAB-M5T1G also features an advanced integrated zero power when the LCD is shut down. This allows for a considerable power saving in comparison to other solutions available in the market. The device has been specifically designed for applications with high power requirements and can provide up to 1.3A per channel and up to 4 channels. Additionally, the device also features a high buck-boost efficiency of up to 95%, allowing for a more efficient power management solution.

Overall, the S-8211AAB-M5T1G is an excellent choice for Battery Management applications. With a wide input voltage range and a patented jitter suppression, the device offers a power efficiency and flexibility that is not found in other solutions available in the market. With integrated OCP and TP protection, the device also ensures reliable operation, making it a great choice for applications where power efficiency and reliability is paramount.
