MAX6946/AX6947's main technical characteristics are as follow. ① 400kbps, 6V withstand voltage, I2C/SMBus-compatible serial interface. ② working voltage is 2.25 ~ 3.6V. ③ when the power is turned on, I / O port is implied in high impedance (it can be synchronized with the turning off of LED) state. ④ I / O port has the 7V overvoltage protection. ⑤ I / O port output type: open-drain output or open-drain logic output when voltage rating is 7V (10mA or 20mA static / PWM output can be synchronized with the LED constant current driver). ⑥ I / O ports support hot insertion. ⑦ each LED can be synchronized with the separate 8-bit PWM brightness control.
