Automotive ET9528
General Description
ET9528 is an Over-Voltage-Protection (OVP) and Over-Current-Protection (OCP) device. It can disconnect IN to OUT to protect load in case wrong input operating conditions are detected. The system is positive over-voltage protected up to 36V. The internal over-voltage thresholds (OVLO) is 6.1V and internal over-current thresholds (OCP) is 2.5A. ET9528 also has internal over temperature protect(OTP) function and it can monitor chip temperature to protect the device.
