ИС беспроводного зарядного устройства P9242-RNDGI

Беспроводной передатчик питания , вход 4.25В до 21В, совместимость WPC 1.2, VFQFN-48

Highly integrated wireless power transmitter with magnetic induction. The device includes an industry-leading 32bit ARM® Cortex®-M0 processor offering a high level of programmability while consuming extremely low standby power. The IC features two LED outputs with pre-defined user-programmable blinking patterns, buzzer and programmable overcurrent protection supporting a wide range of applications. The I2C serial communication allows the user to read information such as voltage, current, frequency and fault conditions. The device includes an undervoltage lockout and thermal management circuit to safeguard the device under fault conditions. Typically used in charging pad, cradle and tablets.
