1 / 6 page TB62781FNG 2011-06-21 1 TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB62781FNG 9-Channel Constant-Current LED Driver of the 3.3V and 5V Power Supply Voltage Operation 1. Features • Power supply voltages: VCC = 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) (IOUT = 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: 150℃) • 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: Topr = −40 to 85°C • Package: SSOP20-P-225-0.65A Absolute Maximum Ratings (Ta = 25 °C) Characteristics Symbol Rating Unit Supply voltage VCC 6.0 V Input voltage VIN −0.3 to VCC + 0.3 (Note 1) V Output current IOUT 85 mA/ch Output voltage VOUT −0.3 to 29 V Power dissipation Pd 1.02 (Notes 2 and 3) W Thermal resistance Rth (j-a) 122 (Note 2) °C/W Operating temperature range Topr −40 to 85 °C Storage temperature range Tstg −55 to 150 °C Maximum junction temperature Tj 150 °C Note 1: However, do not exceed 6.0 V. Note 2: When mounted on a PCB (76.2 × 114.3 × 1.6 mm; Cu = 30%; 35-µm-thick; SEMI-compliant) Note 3: Power dissipation is reduced by 1/Rth (j-a) for each °C above 25°C ambient.
