Description for the LP8861-Q1

The LP8861-Q1 is an automotive high-efficiency, low-EMI, easy-to-use LED driver with integrated boost/SEPIC converter. It has four high-precision current sinks that can provide high dimming ratio brightness control with a PWM input signal.

The boost/SEPIC converter has adaptive output voltage control based on the LED current sink headroom voltages. This feature minimizes the power consumption by adjusting the voltage to lowest sufficient level in all conditions. The boost/SEPIC converter supports spread spectrum for switching frequency and an external synchronization with dedicated pin. A wide-range adjustable frequency allows the LP8861-Q1 to avoid disturbance for AM radio band.

The LP8861-Q1 has an option to drive an external p-FET to disconnect the input supply from the system in the event of a fault and reduce inrush current and standby power consumption. The device can reduce LED current based on temperature measured with external NTC sensor to protect LED from overheating and extend LED lifetime.

The input voltage range for the LP8861-Q1 is from 4.5 V to 40 V to support automotive stop/start and load dump condition. The LP8861-Q1 integrates extensive fault detection and protection features.

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.
