Name

Description

Application Information

DR1

Channel 1 drain sense input

This pin senses the drain voltage of the external MOSFET of channel 1 to

facilitate DHC operation and fault detection.

SE4

Channel 4 sense input

Connect to an external sense resistor to define the Channel 4 LED current.

GD4

Channel 4 gate driver output

Connect to the gate of external NMOS to control the channel 4 LED current.

PGND

Power Ground

Ground for power circuitry. Reference point for all stated voltages. Must be

externally connected to EP and AGND

GD3

Channel 3 gate driver output

Connect to the gate of external NMOS to control the channel 3 LED current.

SE3

Channel 3 sense input

Connect to an external sense resistor to define the Channel 3 LED current.

GD2

Channel 2 gate driver output

Connect to the gate of external NMOS to control the channel 2 LED current.

SE2

Channel 2 sense input

Connect to an external sense resistor to define the Channel 2 LED current.

GD1

Channel 1 gate driver output

Connect to the gate of external NMOS to control the channel 1 LED current.

SE1

Channel 1 sense input

Connect to an external sense resistor to define the Channel 1 LED current.

Thermal Pad (Power Ground)

Used to dissipate heat from the package during operation. Must be electrically

connected to PGND external to the package.
