ET9519中文资料OVP数据手册ETEK规格书

描述 Description

The ET9519 provides complete input over-voltage, input over-current and thermal shutdown protection. When any of the monitored parameters is over the threshold, the IC turn off the charging current. All protections also have deglitch time against false triggering due to voltage spikes or current transients.

ET9519 provides a negative going flag (FLAG) output, which alerts the system that a fault has occurred as overvoltage (power supply or battery voltage), over current or thermal event.
