MPQ7221 is a 16-channel LED driver that operates across a wide 4.5V to 16V input voltage (VIN) range. The MPQ7221 applies 16 internal current sources in each LED string terminal. The LED current (ILED) of each channel is set by an external current-setting resistor, with a maximum current up to 80mA. The MPQ7221 integrates an I2C interface, where 10 different I2C addresses are configurable via an external resistor. This allows the MPQ7221 to support up to 10 cascaded devices to drive the LED array. Each channel can be enabled or disabled via the I2C. The MPQ7221 employs separated pulse-width modulation (PWM) dimming and analogue dimming for each LED channel. Each channel uses 12bit resolution PWM dimming and 6-bit analogue dimming. The ILED ramp rate and phase shift can be configured to optimize the EMI and EMC performance. Applications include automotive taillights, automotive turning lights.
