MAX17511GTL+T

The MAX17511GTL+T is a highly integrated charge pump IC designed to drive mostly low-power, small to medium OLED or STN displays up to 1.4 inches. It operates from a single cell and features two internally regulated supply outputs for the OLED’s negative and positive supply rails, programmable via the low-power I2C interface. Furthermore, the IC fully integrates non-overlapping gated logic level shifters between the display’s controller logic and the display driver logic, including the built-in level-shifting circuit. The IC also provides full protection against short circuits, over current, and thermal conditions.

PMIC - Voltage Regulators - Special Purpose

The MAX17511GTL+T is a voltage regulator special purpose IC in the power management integrated circuits (PMIC) category. A voltage regulator is an electrical regulator designed to automatically maintain a constant voltage level. In power management integrated circuits, the main function of voltage regulator is to convert voltage from a higher level to a lower level. Voltage regulators can also be used in power conditioning, overload protection, and to provide very high tolerances of regulation with minimal current losses. The MAX17511GTL+T is specifically designed to be used in LCD and OLED displays.

Application Field

The MAX17511GTL+T is mainly used in device applications such as mobile phones, PDAs and other handheld devices, where an efficient voltage regulator is needed for power control. The IC operates from a single cell, such as Li-ion or NiMH batteries and ensures a steady, constant supply of clean, regulated power to different parts of the device. It also allows for precision voltage regulation up to 1.2V ±0.1V. This makes the IC useful for low-power display drivers, such as tiny OLED displays, that require a precise amount of power for proper display. Additionally, because the IC does not require any external power supply, the power consumption is reduced, making the IC an ideal choice for portable, battery operated applications.

Working Principle

The MAX17511GTL+T works on the principle of voltage regulation. Its purpose is to ensure that whatever supply voltage is applied, the output voltage remains the same. The IC can be programmed to regulate its output voltage via the low-power I2C interface. In the case of LCD and OLED displays, the IC converts the supplied high voltage to a steady low voltage, which is required to power the display. It also provides full protection against short circuits and thermal conditions, enhancing the devices reliability and integrity.

The MAX17511GTL+T is a highly integrated charge pump IC designed to drive mostly low-power displays up to 1.4 inches. It integrates many features such as non-overlapping gated logic level shifters for enhanced performance and full protection against short circuits, over current, and thermal conditions. These features mean it is ideal for portable applications where space and power efficiencies are important. Finally, the IC can be programmed to provide a precise amount of voltage to the device via the low-power I2C interface, allowing for increased accuracy and reliability.
