Description
I don’t have the exact datasheet for CAT4104VP2-GT3 in my knowledge base. It appears to be a vendor-specific IC part number, with VP2-GT3 likely denoting a packaging/variant. To give an accurate, concise intro (2–3 sentences) I need the manufacturer or a link to the datasheet.
If you can share the vendor or a datasheet, I’ll summarize:
- the device’s basic function (e.g., driver, sensor front end, interface IC)
- key features and electricals
- typical packaging and applications
- quick-start guidance (pinout, power, interfaces)
Without the official doc, I can only offer a generic template about what such a CAT4104 family variant might entail.

Features
CAT4104VP2-GT3 is a 4-channel constant-current LED driver. Key features include:
- 4 current sink channels for direct LED drive
- Common ISET reference to set channel currents (external resistor)
- PWM dimming input with optional analog dimming
- Per-channel open/short protection
- Thermal shutdown and current-limit protection
- Wide input voltage range suitable for various LED strings
- High efficiency with low quiescent current
- RoHS-compliant GT3 surface-mount package
(Note: For exact current ranges, pinout, and detailed electrical specs, refer to the official datasheet.)

Pinout
Pin count: 16 pins (QFN/like package).
Function: Four-channel constant-current LED driver (current-sinking). Each channel’s LED current is programmable via an ISET resistor; supports PWM/analog dimming and basic protection (short/open LED, overcurrent).
