CHY103

CHY103

CHY103是一款USB接口IC,它支持Quick Charge 3.0规范的A类和B类方案。它能够提供多项保护功能,可防止电源及其所连的受电设备(PD)出现输出电压过大、次级侧热过载以及适配器断电后出现功率输出失效。 CHY103接口IC可在启用输出电压调整之前自动检测所连接的受电设备(PD)是兼容Quick Charge 3.0还是Quick Charge 2.0。如果检测到受电设备不兼容Quick Charge 2.0或3.0,CHY103可禁止输出电压调整,以确保仅5 V的旧型USB受电设备能够安全工作。

CHY101

Charger Interface Physical Layer IC with Output Overvoltage Protection

CHY101 is a low-cost USB high-voltage dedicated charging port (HVDCP) interface IC for the Quick Charge 2.0 specification. It incorporates all necessary functions to add Quick Charge 2.0 capability to Power Integrations’ switcher ICs such as TOPSwitch or TinySwitch and other solutions employing traditional feedback schemes. CHY101 supports the full output voltage range of Class A (5 V, 9 V, and 12 V). CHY101 continuously monitors the output voltage and triggers OVP if the actual value exceeds 120% of the set value. CHY101 automatically detects whether a connected Powered Device (PD) is Quick Charge 2.0 capable before enabling output voltage adjustment. If a PD not compliant to Quick Charge 2.0 is detected the CHY101 disables output voltage adjustment to ensure safe operation with legacy 5 V only USB PDs.
