DatasheeDatasheett Constant Current LED Driver with 64 Dimming Steps f or up to 4 LEDs BD1754HFN General Description Key Specification BD1754HFN is a multi-level brightness control LED Operating Power Supply Voltage Range: Driver that works as a constant current driver with 64 2.7V to 5.5V steps, so that the driving current can be adjusted finely. Quiescent Current: 0.1A (Typ) BD1754HFN is best suited to turn ON LEDs that require Operating Temperature Range: -30C to +85 C high-accuracy LED brightness control. Package W(Typ) x D(Typ) x H(Max) Features Current Regulation for up to 4 Parallel LEDs Adjustable Constant Current with 64 Steps High Accuracy and Good Matching of each Current Channel (0.5% Typ) Brightness Control Via Single-Line Digital Control Interface (Uni-Port Interface Control = UPIC) Applications This driver can be used in various applications such as mobile phones, portable game consoles and etc. HSON8 2.90mm x 3.00mm x 0.60mm Typical Application Circuit Power Supply L1 L2 L3 L4 IN C 0.1F IN EN BD1754HFN ISET R ISET 120k GND (When I -max =32mA) LED Product structureSilicon monolithic integrated circuit This product has no designed protection against radioactive rays www.rohm.com TSZ02201-0G3G0C200060-1-2 2012 ROHM Co., Ltd.

Derate by 5.04 mW/C for Ta higher than 25 C. Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings.
