MAX16834AUP+T is an LED driver power management integrated circuit (PMIC), which is specifically designed to control the power of high-brightness LEDs (HBLEDs). It is capable of driving three strings of LEDs, with an operating input voltage range of 4.5V to 27V. It provides up to 800 mA per channel of LED current, adjustable through analog or PWM dimming.The MAX16834AUP+T is used in numerous applications, such as lighting systems, illumination, automotive, portable electronics, and displays.

The MAX16834AUP+T features a buck-boost topology. It employs an internal MOSFET, allowing the device to operate in buck or boost mode depending on the voltage across the LEDs. The MOSFET allows the device to provide reliable energy efficiency and maintain an optimized LED current for each voltage providing close regulation and low ripple. The device also employs adaptive auto-dimming, which is used to reduce the input and output current during low PWM dimming conditions.

The MAX16834AUP+T has programmable operation modes that enable it to meet the needs of various applications. Mode selection is done through the I2C interface. The driver offers a constant current mode, which maintains the regulated LED current regardless of voltage. It also offers a high-speed PWM dimming mode and torchlight mode, which can be used in portable lighting applications.

The MAX16834AUP+T offers advanced protection features that help to protect against current, voltage, and thermal overloads. It offers over-temperature, over-current, and over-voltage protections, and the device has an adjustable under-voltage lockout, which can be adjusted through the I2C interface. The device also features open-LED detection, which helps to detect open LEDs and adjusts the current accordingly.

The device offers an impressive package size of 2.2 mm x 2.5 mm. It operates from a single supply, with an input voltage range of 4.5V to 27V. It has an adjustable output voltage range of 0V to 4.4V and can be used to drive three strings of LEDs. The device also offers a wide range of safety features to protect itself and the LEDs from short-circuits, current and thermal overloads, and open/reverse LEDs.The MAX16834AUP+T is an ideal choice for applications that require accurate and reliable LED dimming and control.
