TB62781FNG
9-Channel Constant-Current LED Driver of the 3.3V and 5V Power Supply Voltage
Operation
1. Features
• Power supply voltages: V_CC = 3.3 V/5 V
• Output drive capability and output count: 80 mA (max)× 9 channels
• Constant-current output range: 5 to 40 mA
• Voltage applied to constant-current output terminals: 0.4 V(min) (I_OUT = 5 to 40 mA)
• Designed for common-anode LEDs
• The input interface is controlled by the SDA and SCLK signal lines.
• Thermal shutdown (TSD) (min: 150ˆ)
• Logical Input signal voltage level: 3.3V and 5V CMOS interfaces (Schmitt trigger input)
• Maximum output voltage: 28 V
• Incorporates PWM control circuitry: Provides seven-bit PWM control.
• Driver identification: Up to 64 drivers can be controlled individually.
• Operating temperature range: T_opr = −40 to 85°C
• Package: SSOP20-P-225-0.65A

However, do not exceed 6.0 V.
When mounted on a PCB (76.2 × 114.3 × 1.6 mm; Cu = 30%; 35-µm-thick; SEMI-compliant)
Power dissipation is reduced by 1/R_{th (j-a)} for each °C above 25°C ambient.
