New from AnalogicTech is the AAT2848, a trimode charge pump driver IC for white LED (WLED) backlight display and flash applications. The device integrates four backlight channels capable of driving up to 30 mA each with two flash channels capable of driving up to 300 mA each, or 600 mA in parallel, in a small 3 m x 3 mm TQFN33-20 package.
To enable, disable and set LED current, the device features two of AnalogicTech's patented simple serial control (S2Cwire) serial digital interfaces. For backlight functions, the device can set current to any of 32 programmable levels. The flash LED outputs can be set independently across 16 programmable levels. Full scale current is independently set for backlight and flash using external resistors.
The driver IC also features an innovative fade-in/fade-out function that gradually increases backlight LED brightness from off to fully on across a 63-step linear progression. Fade time is controllable by an external capacitor. By replacing microprocessor-based software schemes for the same function, this feature offers a smoother transition to full brightness while reducing software overhead.
The device also adds a user-programmable safety timer to protect the flash LEDs from thermal damage. This function can be used to terminate a flash event after a pre-determined period of time. Both the safety timer and flash/strobe operation are enabled via a separate flash enable pin.
The AAT2848 integrates short-circuit and over-temperature protection, while soft start circuitry prevents excessive inrush current at start-up and during mode transitions.
Qualified across the -40°C to +85°C temperature range, it is available in a lead-free, 20-pin TQFN package.
