Overview

The RT4801HWSC from Richtek is a dual output LCD bias for smartphones and tablets 15 pin WLCSP package. This is a highly integrated boost and LDO and inverting charge pump to generate positive and negative output voltage. The output voltages can be adjusted from ±4V to ±6V with 100mV steps by I2C interface protocols. With its input voltage range of 2.5V to 5.5V. The RT4801HWSC is optimized for products powered by single-cell batteries and symmetrical output currents up to 80mA. Both positive and negative voltages can be programmed by a MCU through the dedicated I2C interface. It provides Overtemperature protection (OTP) and short circuit protection (SCP) mechanisms to prevent the device from damage with abnormal operations. It is used in TFT-LCD smartphones, TFT-LCD tablets and general dual power supply applications.
