IV. Industry Application Cases: SIC's Diversified Customer Value
1. Consumer Electronics: Enabling Rapid Iteration of Smart Devices
Customer Requirement: A mobile phone manufacturer needs to integrate ALS and a proximity sensor into a new model, requiring power consumption < 2mW, detection error < 5%, and compatibility with a compact PCB space.
SIC Solution:
Recommended Broadcom AP3216C (integrated ALS + proximity sensor, size 2mmx2mm), paired with Allegro A8304SESTR-T (3mmx3mm QFN package), achieving dynamic voltage regulation (3.3V±2%) via the I²C interface.

V. Deep Collaboration with Allegro: Power Management Empowering Distribution Value
SIC takes Allegro's power management chips as the core support for light sensor solutions, enhancing customer system performance through "sensing + power supply" collaborative optimization:
Necessity of Low-Noise Power Supply:
The ADC of light sensors is sensitive to power ripple. For example, a 16-bit ADC in an ambient light sensor may produce LSB errors when ripple > 100μVrms. Allegro A8304's 704kHz switching frequency combined with a high-frequency inductor can suppress ripple below 50μVrms, ensuring detection accuracy.
Dynamic Current Matching Technology:
The peak current of the IR sensor emitter can reach 1A (such as when multi-wavelength LEDs are activated simultaneously). A8304's adjustable current limit (250-950mA) and temporary current boost function (+25%) can dynamically adapt to load changes, avoiding false triggering of overcurrent protection while reducing average power consumption through pulse power supply mode.
Thermal Management and Miniaturization Design:
A8304's 3mmx3mm QFN package is compatible with the compact layout of light sensor modules. The exposed pad is connected to the metal housing via thermal grease, with a thermal resistance (RthJA) as low as 25K/W, suitable for space-constrained wearable devices and automotive scenarios.
