SGL8022W Single-channel DC LED touch control chip SOP-8

SGL8022W Single-Channel DC LED Touch Control Chip (SOP-8) offers a responsive and power-efficient solution for touch-based LED control. Designers can integrate it into lighting fixtures, touch panels, and control boards to enable single-channel brightness control with simplicity and precision.

Key Features:

• Single-Channel Touch Control: Directly manages one LED channel using touch input.
• Low Power: Consumes minimal standby and active power for energy-conscious designs.
• SOP-8 Package: Fits standard surface-mount PCB layouts.
• Fast Response: Delivers immediate LED dimming/fading when users interact.
• Stable Performance: Ensures reliable operation across commercial temperature range.

Technical Specifications:

• Operating Voltage: Typically 5 V DC (check datasheet for range)
• Control Method: Capacitive or resistive touch sensing input
• Output: PWM or analog dimming drive (single-channel)
• Current Handling: Suitable for LED drive (refer to thermal limits)
• Temperature Range: –40 °C to +85 °C ambient

Mechanical Specifications:

• Package Type: SOP-8 (surface-mount)
• Pin Material: Tin-plated leads
• Body Material: Epoxy resin housing

Dimensions:

• Package Footprint: Approx. 3.9 mm × 4.9 mm
• Lead Pitch: 1.27 mm
• Lead Length: ~0.5 mm from body

Pinout and Wiring:

• Pin 1: Touch input
