概述

Description

CAT4104VP2-GT3 is a four-channel constant-current LED driver IC (from Catalyst Semiconductor, now ON Semiconductor). It provides four current sinks to drive up to four LED strings from a single supply. Each channel’s current is set externally (RSET). Dimming is supported via PWM and/or analog dimming inputs. Protections typically include open/short LED detection and thermal shutdown. The GT3 suffix denotes a specific packaging/variant (lead-free) of the device.
Common uses include LCD/backlight, display backlighting, and decorative lighting. To get started: obtain the latest datasheet for the VP2-GT3 variant, verify the pinout, calculate RSET for your desired per-channel current, connect the LED strings to the four outputs, and drive the dimming inputs while providing proper decoupling and thermal management. Always refer to the datasheet for exact electrical specs, operating ranges, and recommended application circuits.

Features

CAT4104VP2-GT3 features (concise):
- 4-channel constant-current sink outputs for LED strings
- Common current set by a single external resistor (matched per channel)
- PWM dimming input for brightness control
- Protection on each channel: open-LED, short-circuit; plus undervoltage and over-temperature protection
- Wide input voltage range suitable for backlight/display LEDs
- Pb-free GT3 package (RoHS-compliant) suitable for compact designs
Applications: LED backlighting, displays, signage.

Package

Equivalent

I don’t have a real-time cross-reference for CAT4104VP2-GT3. Exact equivalents depend on specs. Please share key details or the datasheet: per-channel current, supply voltage range, dimming method (PWM/analog), package GT3, and tolerance. With those, I can suggest precise cross-ref parts from TI, Analog Devices, Renesas, Microchip, etc.
