Additional Infomation About Product

LED1202 Datasheet 12-channel low quiescent current LED driver Features Supply range from 2.6 V to 5 V 12 channels for single LED 20 mA current capability per channel 1% (typ.) current matching at 16 mA and 2% (typ.) at 2.5 mA WLCSP20 1.8 V compatible IC control interface 8-bit analog dimming individual control 12-bit local PWM resolution 8 programmable patterns Programmable pattern sequence Synchronization for multi-device application Phase shifting between channels QFN20 3x3 Open LED detection Overtemperature protection 8 configurable IC slave addresses plus global address Fault flag pin Applications RGB LED lighting, fade-in and fade-out breathing effect, indicator lights for: Wearable electronics Battery powered devices Maturity status link Portable accessories LED1202 Description The LED1202 is a 12-channel low quiescent current LED driver it guarantees 5 V output driving capability and each channel is able to provide up to 20 mA with a headroom voltage of 350 mV (typ.) only. The output current can be adjusted separately for each channel by 8-bit analog and 12-bit digital dimming control. A slow turn-on and turn-off time improves the system low noise generation performance moreover, the phase shifting function helps to reduce the inrush current. Eight patterns can be stored in the internal registers for automatic sequencing without MCU intervention. The pattern sequence can be also configured for duration time and number of repetition. For multi-device applications, a common clock domain can be shared for timing synchronization. The device includes thermal shutdown and open LED detection. The device IC interface is based on fast mode specification and works up to 400 kHz. Eight IC addresses are possible by using two configuration pins (A0/A1) only. The LED1202 is available in WLCSP20 package 1.71 x 2.16 x 0.5 mm with 0.4 mm pitch and in QFN20 3x3 package 3 x 3 x 0.6 mm with 0.5 mm pitch.
