General Description

The ET9519 provides complete Li+ charger protection against Input over-voltage, input over-current and thermal shutdown protection is also available. When any of the monitored parameters is over the threshold, the IC turns off the charging current. All protections also have deglitch time against false triggering due to voltage spikes or current transients. The system is positive over-voltage protected up to +30V. Thanks to a very low current consumption, the USB charge is compatible with this integrated component.
