RT7202K

Highly Integrated USB PD Type-C Controller for SMPS

General Description

Features

^Protocols Supported

The RT7202K is a simple and yet flexible for multipurpose

of USB PD controller. By programming, it could operate

as a source or a sink.

^USB PD 2.0 and 3.0 (PPS)

^Other Proprietary Protocols

^Highly Integrated

When used as a source, it could be used in an off-line

AC-DC converter, as it integrates shun regulator, constant

voltage (CV) and constant current (CC) control loop with

programmable reference voltage to meet the specification

of Programmable Power Supply (PPS) specification. When

combined with external buck or buck boost controller, it

could constitute aDCDC converter, such as a car charger

, and could also meet the PPS specification. When used

as a sink, it is simple, low cost, yet flexible to use to

request required power from a source. If using the

RT7202KD for a sink design, it has I²C interface and two

GPIOs for flexible use and could be easily controlled by

other MCU which plays a master role.

^Embedded MCU with an Mask-ROM of 24kB, an

OTP-ROM of 8kB, and an SRAM of 2kB

^Embedded BMC Transceiver

^Wide V_DDOperation Range : 3V to 22V

^Built-in Shut Regulator for Constant-Voltage

and Constant-Current Regulation

^Built-in 10-bit Analog-to-Digital Converter (ADC)

^Programmable Cable Compensation

^BLD Pin for Quick Discharge of Output Capacitor

(RT7202KD)

^VDD Pin for Quick Discharge of Output Capacitor

(RT7202KE/KF)

^USBP Pin for Direct Drive of External Blocking

N-MOSFET
