RT7204E Datasheet | Richtek

Description The RT7204E is a highly integrated, programmable controller that offers multi-protocol support and features high-precision shunt regulators for constant voltage (CV) and constant current (CC) regulation. An embedded MCU is designed to handle customized functions with flexibility, ensuring patibility with USB PD protocol, Universal Fast Charging Specification (UFCS), and proprietary protocols via the CC1, CC2, D+, and D- interface. This controller is specifically designed for off-line ACDC converters to achieve the high power density of a fast charging system. The RT7204E is equipped with rectification detection to sense the AC input voltage and adaptively configure the power rating. Additionally, it monitors the PWM switching state to detect AC OFF conditions. For safety considerations, the RT7204E provides prehensive protections, including Limited Power Source (LPS) protection and precise internal Over-Temperature Protection (OTP). Furthermore, the RT7204E can also share the output power through I2C munication for multi-port applications. The remended junction temperature range is - 40C to 125C, and the ambient temperature range is - 40C to 105C. 2 Applications - USB Type-C Controller in Source Applications for Single-Port or Multi-Port Charger / Adapters of Smartphone, Tablet, Notebook, and Other Electronics 3 Features - Protocol Support - USB PD 3.1 and PPS - Universal Fast Charging Specification (UFCS) - Proprietary Protocols - Highly Integrated - Suited for 3V to 21V VDD Range - Built-In Shunt Regulators for Constant Voltage and Constant Current Control - Built-In 11-bit Analog-to-Digital Converter (ADC) - Built-In Linear Regulator - Built-In Blocking N-MOSFET Driver with Soft Start for Capacitive Load - VDD Quick Discharge for Output Capacitor - Built-In Output Bleeder for Quick VBUS Discharge - Support High-Side Current Sensing - Support Programmable Cable pensation - Support Input Voltage (VIN) Detection - Support Slave I2C munication -...
