Description for the LM8502

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 VOUT or 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.

The LM8502 has two inputs for Ambient Light Sensing — together with the PWM input they enable Dynamic Backlight Control. The LM8502 may also be used for haptic motor driving instead of flash. When the device is idle, featured Power-save mode and use of an external clock reduce current consumption significantly.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
