DESCRIPTION
It can work with external USB PD controllers via the I2C interface. The I2C interface and one-time programmable (OTP) memory provide flexibility for configurable features. Fault condition protections include constant current (CC) current limiting with a high-side (HS) current sense, output over-voltage protection (OVP), and thermal shutdown (TSD). The MP4248 requires a minimal number of readily available, standard external components, and it is available in a QFN-20 (3mmx5mm) package.FEATURES
