目录产品概述 返回TOP CXPR78103是一款高侧过压保护( OVP ) IC，它可以维持高达32V的电压，保护下游器件免受高压浪涌的影响。 CXPR78103采用CSP2×3-6封装 CXPR78103 is an Over-Voltage-Protection (OVP) IC with an ultralow 45mΩ RDSON high current high voltage MOSEFT. It can sustain voltage as high as 32V DC, protecting downstream devices from high voltage surges. When input voltage of CXPR78103 exceed the OVP threshold, it responses quickly and shuts off the MOSFET. The OVP threshold can be externally adjustad with resistors at OVLO pin. There is also an over-current-protection feature for the switch. When overload condition occurs, it goes into a hiccup mode to protect the IC from over-heating. It also has an overtemperature protection feature that turns off the MOSFET. 产品特点 返回TOP Over voltage protection up to 32V 45mohm switch resistance Externally adjustable OVP voltage 60ns Fast Transient response Internally set current limit 应用范围 返回TOP Smart Phone Car camera Power bank 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ | |||||||||||||||||||||||||||||||||||||||||||
