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。
当CXPR78103的输入电压超过OVP阈值时,它会快速响应并关闭MOSFET。OVP阈值可通过OVLO引脚上电阻进行外部调整。当过载情况发生时,它进入打嗝模式以保护IC免于过热。它还具有过温保护功能,可关闭MOSFET。 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.
