Product details

Overview

VEML60311X01-GS15 from Vishay Semiconductors is a high-accuracy ambient light sensor IC with 16-bit digital output, Filtron™ human-eye spectral response, AEC-Q101 qualification, and I²C interface (7-bit address 0x10). It delivers ±10% typical ALS output tolerance across light sources, 0.0026 lx/ct resolution at 400 ms integration time, and operates from 2.5 V to 3.6 V supply in automotive display backlight control systems.

For engineers reviewing the VEML60311X01-GS15 datasheet, VEML60311X01-GS15 pinout, VEML60311X01-GS15 application, or VEML60311X01-GS15 equivalent, this page provides verified technical context, I²C register mapping, temperature-compensated lux calculation parameters, and automotive-grade design constraints - all confirmed against Vishay Document #80008 Rev. 1.1.

Technical Context

The VEML60311X01-GS15 integrates a photodiode, low-noise amplifier, and 16-bit ADC into a single die with dual-channel output (ALS + IR), supporting programmable gain (x0.5 to x2), integration time (3.125–400 ms), and photodiode division (4/4 or 1/4 PD). Its I²C interface complies with Standard and Fast modes (10–400 kHz) and features interrupt-driven threshold detection with persistence counters.

It implements auto-memorization for retained ALS data during shutdown, hardware-level temperature compensation validated from −40 °C to +125 °C, and dark offset correction (≤4 LSB at 200 ms IT). The device uses Filtron™ optical filtering to match CIE photopic luminosity function within ±10% under 4300K white LED, fluorescent, and incandescent illumination.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	2.5 V to 3.6 V - supports direct connection to automotive 3.3 V rails without LDO; I²C bus voltage range independent (1.7–3.6 V)
Ambient Light Range	0 lx to 172,000 lx - enables full-spectrum operation from dark cabin to direct sunlight exposure
Resolution	0.0026 lx/step (at ALS_GAIN = x2, ALS_IT = 400 ms, PD_DIV = 4/4) - allows precise dimming control under low-transmittance lens designs
Output Format	16-bit I²C digital ALS data (registers 0x10–0x11) - eliminates external ADC requirement and reduces system BOM count
Operating Temperature	−40 °C to +125 °C - qualified per AEC-Q101 for under-hood and infotainment module deployment
Shutdown Current	Typ. 0.5 μA - enables ultra-low-power sleep mode in battery-backed automotive modules
I²C Slave Address	0x10 (7-bit) - distinct from VEML6031X01 (0x29); avoids bus conflicts in multi-sensor systems

Pinout & Package

Package: Surface-mount, miniature opaque 2.67 mm × 2.45 mm × 0.6 mm (Vishay drawing 6.550-5357.01-4), MSL 2a, 4-week floor life.

Pin/Terminal	Circuit Role	Design Meaning
1 GND	Ground reference	Dual ground pins (1 & 4) reduce noise coupling; exposed pad (pin 1 marking dot) must be soldered for thermal and EMI performance
2 SDA	I²C data line	Open-drain, requires external pull-up (2.2–4.7 kΩ); compatible with 1.7–3.6 V logic levels regardless of VDD
3 INT	Interrupt output	Open-drain active-low signal; triggers on ALS threshold crossing (configurable low/high windows and persistence)
4 GND	Ground reference	Second ground terminal improves return path integrity for analog sensing circuitry
5 SCL	I²C clock line	Input-only, accepts 10–400 kHz clock; rise/fall times ≤300 ns ensure reliable fast-mode timing
6 VDD	Power supply	2.5–3.6 V input; decoupling capacitor ≥100 nF required adjacent to pin for ADC stability

Key Features

Feature	Design Value
Filtron™ spectral matching	Human-eye photopic response (CIE 1931) with ≤10% deviation across white LED, fluorescent, and incandescent sources
Temperature-compensated ALS output	±0.5% typical deviation over −40 °C to +125 °C (Fig. 8), eliminating need for host MCU calibration routines
Auto-memorization	Retains last valid ALS reading during shutdown; accessible via I²C read without wake-up delay
Configurable interrupt engine	Independent high/low threshold windows (16-bit registers 0x04–0x07) with 1/2/4/8-event persistence to suppress false triggers
Multi-gain & integration time control	Four ALS gain settings (x0.5 to x2) and eight integration times (3.125–400 ms) enable dynamic range optimization per lighting condition
AEC-Q101 qualification	Validated for automotive applications including display backlight, rearview mirror dimming, and HUD brightness control
