The EV7221-R-00A is an evaluation board designed to demonstrate the capabilities of the MPQ7221-AEC1. The MPQ7221 is a 16-channel LED driver that can operate across a wide 4V to 16V input voltage (V_IN) range. The MPQ7221 applies 16 internal current sources in each LED string terminal. The LED current of each channel is set by an external current-setting resistor. The maximum current of each channel is 80mA.

The MPQ7221 integrates a serial interface. Ten different addresses are configurable via an external resistor, which allows the MPQ7221 to support up to 10 cascaded ICs to drive an LED array. Each channel can be enabled or disabled via the serial interface. The MPQ7221 employs separated pulse-width modulation (PWM) dimming and analog dimming per LED channel, as well as 12-bit resolution PWM dimming and 6-bit analog dimming per channel. The LED current ramp rate and phase shift can be configured to minimize electromagnetic interference (EMI).

The MPQ7221 can output a configurable refresh signal from the RFSH/FLT pin. The driver integrates open-load protection (OLP), short-load protection (SLP), and over-temperature protection (OTP). The fault indicator is pulled low when any protection is triggered, and the corresponding fault register is set.

The MPQ7221 is AEC-Q100 qualified, and is available in a QFN-24 (4mmx4mm) package with wettable flanks.
