Monolithic Power Systems (MPS) EV7221-R-00A Evaluation Board

Monolithic Power Systems (MPS) EV7221-R-00A Evaluation Board is designed to demonstrate the capabilities of the MPQ7221-AEC1 16-channel LED driver. The MPQ7221-AEC1 driver operates across a 4V to 16V input voltage range. This evaluation board features an I2C interface, 40μs phase shift, LED open protection, 80mA LED current/string, Under-Voltage Lockout (UVLO), and Over-Temperature Protection (OTP). The EV7221-R-00A evaluation board is available in dimensions of 6.35cm x 6.35cm x 2cm and is AEC-Q100 qualified. Typical applications include automotive taillights and automotive turning lights.
