LP8501TME/NOPB General Description

One of the key features of the LP8501 is its high-efficiency charge pump, which allows for LED driving across the entire Li-Ion battery voltage range. The device autonomously adjusts the charge pump gain based on the requirements of the LED forward voltage, ensuring optimal efficiency at all times. Additionally, the LP8501 has a power-save mode that activates when LED outputs are inactive, reducing idle current consumption to as low as 10 µA (typ.)

Key Features

9 Programmable Source (High Side) Driver Outputs with 25.5 mA Full-Scale Current, 8-bit Current Setting Resolution and 12-Bit PWM Control Resolution
Flexible Grouping Possibility for All 9 Outputs Including GPO into Three Groups with Group PWM and Fade-In/ Fade-Out Controls
Built-in LED Test
Adaptive Charge Pump with 1x and 1.5x Gain Provides up to 95% LED Drive Efficiency, with Soft Start and Overcurrent/Short Circuit Protection
Automatic Power Save Mode; I_VDD = 10 µA (typ.)
Two Wire, I²C-Compatible, Control Interface
Small Application Circuit
Pin-configured LED Powering for LEDs 1 to 6 and for LEDs 7 to 9
Solution Area <18 mm²
