N1.6 Characteristics subject to change without notice ABSOLUTE MAXIMUM RATINGS Parameter Rating Unit VIN, LEDx voltage -0.3 to 6 V VOUT voltage -0.3 to 6 V EN, CTRL0, CTRL1, CTRL2 voltage VIN + 0.7V V Storage Temperature Range -65 to +150 °C Junction Temperature Range -40 to +125 °C Soldering Temperature (10s) 300 °C ESD protection HBM 2 kV NOTE: Stresses listed above may cause permanent damage to thje device. Functional operation of the device at these or any other conditio ns beyond those indicated in the “Recommended Operating Conditions” is not impiled. Exposure to abslute maximum rating conditions for extended periods may remain possibility to affect device reliability. RECOMMENDED OPERATING CONDITIONS Parameter Rating Unit VIN 2.7 to 5.5 V Ambient Temperature Range -40 to +85 °C ELECTRICAL OPERATING CHARACTERISTICS (Over recommended operating conditions unless specified otherwise) VIN = 3.6V, EN = High, TAMB = 25°C Name Conditions Min Typ Max Units Quiescent Current ILED = 20mA per channel 1.3 1.5 mA Shutdown Current EN = 0V 0.1 1 µA RSET = 24k 20 LED Current RSET = 96k 5 mA LED Current Setting Range 2.7 < VIN < 5.5V 2 30 mA LED Current Accuracy To set value -8 3 +8 % LED Channel Matching (ILED MAX - ILED MIN) / (ILED MAX + ILED MIN) -5 3 +5 % Current Sink Dropout Voltage* 20 30 mV Short Circuit Output Current Limit VOUT = 0V 22 25 mA High Input Voltage = VIN 1 Leakage Current Low Input Voltage = 0 -1 µA High 1.3 EN, CTRL0, CTRL1, CTRL2 pins Logic Level Threshold Low 0.4 V PWM frequency 100 100000 Hz PWM duty cycle 1 100 % Thermal Shutdown 150 Thermal Hysteresis 20 °C Under Voltage Lockout (UVLO) Threshold 2.4 V *) Voltage drop at led pin, at which LED current falls 10% below set value |
