JX2212 过压保护芯片
产品介绍
The JX2212 is an Over-Voltage-Protection (OVP) and Over-Current-Protection (OCP) IC with adjustable OCP thresholds current.
It can disconnect IN and OUT to protect load when wrong input operating conditions are detected. The maximum operation voltage and current of JX2212 are 36V and 2A.
The internal default over-voltage thresholds is 6.1V .
The maximum operation current of JX2212 is 2A, over current protection will be triggered if operation current is large than 2.3A with ISET pin floating, and the OCP current decreases if Rset is defined, as the value of Rset increases,the OCP current decreases.
JX2212 also has internal over temperature protection (OTP) function, it can monitor chip temperature to protect the device.
