LP8861QPWPRQ1 Typical application Circuitry

LP8861QPWPRQ1

The LP8861QPWPRQ1 is a high-efficiency LED driver with integrated boost converter designed by Texas Instruments. It finds its application in automotive displays, including clusters and center stack displays. Let's delve into the detailed connection methodology for the LP8861QPWPRQ1, with emphasis on its specific pins:

1. VIN (Pin 1): Connect this pin to the input voltage supply. The LP8861QPWPRQ1 can handle a wide input voltage range, so ensure to follow the specifications as per your application requirements. Input capacitors should be placed close to this pin for stability.

2. GND (Pin 2-3, 24-25): Ground connections for the LP8861QPWPRQ1. Multiple ground pins are provided for better thermal performance and noise immunity. Connect these pins to the system ground plane.

3. EN (Pin 4): This is to enable pin for the LP8861QPWPRQ1. Apply a logic-high signal to turn on the chip, and a logic-low signal to turn it off.

4. SCL/SDA (Pin 5-6): These pins are used for I2C communication with the LP8861QPWPRQ1. Connect them to the corresponding I2C bus lines of your microcontroller or host device.

5. PWM (Pin 7): The LP8861QPWPRQ1 allows PWM dimming through this pin. Connect it to a PWM signal source if this functionality is required in your design.

6. SYNC (Pin 8): This pin is used to synchronize the internal oscillator of the LP8861QPWPRQ1 with an external clock if needed.

7. FAULT (Pin 9): A fault signal output from the LP8861QPWPRQ1. It can be monitored by a microcontroller to detect any issues in the LED driver's operation.

8. LED Outputs (Pin 10-17): These are the LED current sink outputs from the LP8861QPWPRQ1. Connect them to the anodes of the LEDs as per your configuration.

9. BST (Pin 18): Connect a bootstrap capacitor between this pin and the SW pin of the LP8861QPWPRQ1 for proper operation of the internal boost converter.

10. SW (Pin 19): Switch node connection for the LP8861QPWPRQ1's boost converter. Inductor and diode connections should be made here.

11. OUT (Pin 20-21): Output voltage pins. Place output capacitors close to these pins, as specified in the data sheet of the LP8861QPWPRQ1.

12. AND (Pin 22): Analog ground pin for the LP8861QPWPRQ1. Connect to the system ground.

13. ADD (Pin 23): Connect this pin to the analog supply voltage as specified for the LP8861QPWPRQ1.

In summary, proper connection of these pins, along with adherence to the data sheet recommendations, will ensure an efficient and reliable operation of the LP8861QPWPRQ1 in your automotive display or other LED-driven applications. The LP8861QPWPRQ1 offers flexibility and advanced features that make it a versatile choice for contemporary lighting solutions.
