GENERAL DESCRIPTION
The ADP8861 provides a powerful charge pump driver with
independent control of up to seven LEDs. These seven LEDs
can be independently driven up to 30 mA (typical). The seventh
LED can also be driven to 60 mA (typical). All LEDs are pro-
grammable for maximum current and fade in/out times via
the I2C interface. These LEDs can also be combined into groups to
reduce the processor instructions during fade in/out.
This entire configuration is driven by a two-capacitor charge
pump with gains of 1×, 1.5×, and 2×. The charge pump is
capable of driving a maximum IOUT of 240 mA from a supply
of 2.5 V to 5.5 V. A full suite of safety features, including short-
circuit, overvoltage, and overtemperature protection, allows
easy implementation of a safe and robust design. Additionally,
input inrush currents are limited via an integrated soft start
combined with controlled input-to-output isolation.
The ADP8861 is available in a compact lead frame chip scale
package (LFCSP).
