Description
General part information
LM8502 Series
The LM8502 is a versatile LED driver suitable for multiple applications. It includes a 2MHz, fixed-frequency synchronous boost converter, 10 current sink LED outputs, 2 outputs for flash or haptic applications, ambient light sensing and PWM input.
The 10 current sink LED outputs offer individual current control through an I2C-compatible interface. Current can be accurately controlled with a full-scale setting and 8-bit current control. The LM8502 also enables LED control with group faders and lighting engines. Group faders enable single I2C register writes for multiple LED outputs with fading, whereas lighting engines with SRAM memory enable engine-driven lighting sequences. Each LED output can be powered either from VOUTor an external voltage supply.
The flash function is capable of driving 2 LEDs, each having 600 mA maximum current, or a single LED up to a 1.2A maximum current. A hardware flash enable provides a direct interface to trigger the flash pulse. Dual TX inputs allow the flash to be synchronized with the RF power system to prevent excessive current draw from the system power supply. The LM8502 also offers LED thermal sensing as a safety procedure for flash and separate indicator LED.
