MPQ7221 16-Channel LED Drivers

Monolithic Power Systems (MPS) MPQ7221 16-Channel LED Drivers operate across a wide 4.5V to 16V input voltage (V_IN) range. These LED drivers integrate an I²C interface, where ten different I²C addresses are configurable via an external resistor. The MPQ7221 LED drivers apply 16 internal current sources in each LED string terminal. The LED current of each channel is set by an external current-setting resistor, with up to 80mA maximum current. These LED drivers employ separated Pulse Width Modulation (PWM) dimming and analog dimming to reach the LED channel. Each channel utilizes 12-bit resolution PWM dimming and 6-bit analog dimming.
