The MAX8821ETI+T from Analog Devices / Maxim Integrated is a versatile power management IC designed for applications requiring LED driving, audio amplification, and regulated power. It integrates a high-efficiency, adaptive-mode inverting charge pump capable of driving up to six white LEDs with constant current, adjustable via an I2C interface from 0.1mA to 25.6mA per LED.
The device also includes a 2W mono Class D audio amplifier with proprietary filterless Active Emissions Limiting (AEL) technology, offering up to 2W into a 4 Ω speaker. The amplifier's gain is adjustable from -3dB to +24dB through the I2C interface, and it features integrated click-and-pop suppression.
Furthermore, the MAX8821ETI+T incorporates two low-noise LDOs, each with individually programmable output voltages via I2C. These LDOs provide a high 70dB PSRR rating. The IC includes essential protections such as soft-start, thermal shutdown, open-circuit, and short-circuit protection.
Packaged in a compact 28-pin, 4mm x 4mm Thin QFN package with an exposed pad, the MAX8821ETI+T is suitable for space-constrained designs. Its operating temperature range is -40°C to 85°C (TA).
