As1109 Bqft
Overview
Product sourcing insights & recommendations
The phrase "as1109 bqft" refers to a high-precision, 8-channel constant-current LED driver integrated circuit (IC) manufactured by ams OSRAM. This specific component is primarily used in high-resolution LED displays, video walls, and industrial signage due to its advanced diagnostic capabilities Ams-OsramDigikey.
Market Status & Insights
* Production Status: The AS1109-BQFT is officially Discontinued / Obsolete. A formal discontinuation notice was issued in December 2021, and it is no longer in active production Ams-OsramDigikey.
* Supply Chain: While obsolete at major retail distributors like DigiKey or Mouser, stock is still actively traded on the secondary B2B market. Multiple suppliers in Shenzhen, China, currently list "New Original" stock with prices ranging from $0.76 to $0.79 per unit for bulk orders AlibabaAlibaba.
Core Technical Product Features
* Precision Control: Drives 8 channels at up to 100mA each with high accuracy, ensuring uniform brightness across large LED arrays JotrinDigikey.
* Diagnostics: Features on-chip "flicker-free" testing that detects open or shorted LEDs without interrupting the visual display Ams-Osram.
* Performance: Operates on a high-speed 50MHz SPI interface, supporting high-resolution Pulse Width Modulation (PWM) for smooth dimming JotrinMouser.
Market Trends & Alternatives
The market is shifting away from the AS1109 toward more modern or readily available equivalents. If you are designing new hardware or maintaining existing systems, consider the following functional substitutes:
| Equivalent Part | Manufacturer | Key Comparison |
|---|---|---|
| STP08DP05 | STMicroelectronics | Direct Functional Match: 8-channel, 100mA, 16-QFN. Lower clock speed (30MHz) but higher output voltage (20V) StMouser. |
| AS1115-BQFT | ams OSRAM | Modern Successor: Features an I2C interface instead of SPI and includes integrated key-scanning for user interfaces Lisleapex. |
| PCA9745B | NXP | Higher Density: 16-channel SPI driver for high-density applications, though it requires a different footprint Nxp. |
