LM3535TME

The LM3535TME is a highly integrated LED driver capable of driving 8 LEDs in parallel for large display applications. It provides multi-zone Ambient Light Sensing (1 or 2 ALS inputs depending on option) allowing autonomous backlight intensity control in the event of changing ambient light conditions and is available in National's tiny 20-bump, 0.4mm pitch, thin micro SMD package.

The features of LM3535TME can be summarized as:(1)Drives up to 8 LEDs with up to 25mA of Diode Current Each; (2)External PWM input for Dynamic Backlight Control; (3)Multi-Zone Ambient Light Sensing (ALS); (4)Dual-ALS Sensor Inputs (LM3535-2ALS only); (5)ALS Interrupt Reporting; (6)Independent On/Off Control for all Current Sinks; (7)128 Exponential Dimming Steps with 600:1 Dimming Ratio for Group A (Up to 6 LEDs); (8)8 Linear Dimming States for Groups B (Up to 3 LEDs) and D1C (1 LED); (9)Programmable Auto-Dimming Function; (10)Up to 90% Efficiency; (11)0.55% Accurate Current Matching; (12)Internal Soft-Start Limits Inrush Current; (13)True Shutdown Isolation for LEDs; (14)Wide Input Voltage Range (2.7V to 5.5V); (15)Active High Hardware Enable; (16)Total Solution Size < 16mm2; (17)Low Profile 20 Bump micro SMD Package(1.650mm*2.055mm*0.6mm).

The absolute maximum ratings of LM3535TME are:(1)VIN pin voltage:-0.3V to 6.0V; (2)SCL, SDIO, HWEN, PWM pin voltages:-0.3V to (VIN+0.3V)w/ 6.0V max; (3)IDxx Pin Voltages:-0.3V to (VVOUT+0.3V)w/ 6.0V max; (4)Continuous Power Dissipation:Internally Limited; (5)Junction Temperature (TJ-MAX):150°C; (6)Storage Temperature Range:-65°C to +150° C; (7)Maximum Lead Temperature(Soldering)ESD RatingHuman Body Model:2.0kV.
