Product Overview
AWP36410ACSRis a boost single-channel flashlight driver IC integrated with breathing light modeboost, supporting input voltage fromsilicon anode batteries. It featuresultra-high flashlightcapability and(torch)a compact and thin form factor, making it suitable for scenarios such as smartphones, tablets, gimbals, action cameras, smart home appliances, and small handheld lighting devices.
Product Advantages
AWP36410ACSR is a boost‑mode flash LED driver integrating a precision programmable constant‑current source. The single channel delivers up to 1.5 A drive capability, supporting both powerful flash bursts and delicate, dynamic lighting effects. It all‑in‑one covers five operating modes: Flash, Torch, Double Torch, IR infrared fill‑light, and Breath light.
Compared with competing devices on the market, the AWP36410ACSR offers the following advantages:
-
Higher efficiency: Approximately 5% higher efficiency in both Flash and Torch modes.
-
Wider voltage range: The minimum operating voltage can go down to 2.2 V, well‑suited for silicon‑anode battery applications, while competitors typically operate from 2.5 V‑2.7 V.
-
Fine‑tunable drive current: Against competitors’ 128‑step dimming, the AWP36410ACSR provides 256‑step dimming for more precise user‑case matching.
-
Newly‑added Breath‑light mode: Compared with conventional boost flash drivers, this device introduces a breath‑light mode with up to 1024‑level fine dimming. It achieves smooth light‑and‑shadow transitions for advanced bionic breathing dynamics, enabling expanded human‑machine interaction designs and improved user experience.
-
Double Torch current: Enables migration from basic flashlight functionality to multi‑function devices. Increased illumination distance and brightness directly enhance night‑time safety performance.
-
Enhanced protection suite: Beyond the full set of protection functions offered by competitors, it adds more configurable options for IVFM (Input‑Voltage‑Based Flash‑Magnitude optimization) and TSB (Thermal‑Smart‑Bias configurable thermal derating protection). Users may freely configure parameters via registers.
-
More compact package: While maintaining pin‑to‑pin compatibility, it achieves a 17% reduction in die area versus the smallest competing alternative.
