产品介绍
• Power supply voltages: VDD = 3.3 V/5 V • Output drive capability and output count: 50 mA (max)× 8 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) • Current adjustment (via 7-bit serial data): The MSB, or the HC bit, selects the output current range: 25% to 50% range when HC = 0 or 50% to 100% range when HC = 1 The six LSB bits are used to adjust the current in 64 steps within the selected range. • Designed for common-anode LEDs • Thermal shutdown (TSD) (min: 150°C) • Power on reset (POR) • Output-open detection (OOD) and output-short detection (OSD) • Logical input signal voltage level: 3.3-V and 5-V CMOS interfaces (Schmitt trigger input) • Maximum output voltage: 25 V • Serial data transfer rate: 25 MHz (max) @cascade connection • Operating temperature range: Topr = −40 to 85°C • Package: SSOP16-P-225-0.65B • Constant-current accuracy |
