产品概述 返回TOP
The CXPR7158/A provide Li+ charger protection against over-voltage. The IC is designed to monitor input voltage. When input voltage is over the threshold, the IC removes the power from the charging system by turning off an internal switch. The protection also have deglitch time against false triggering due to voltage spikes. The CXPR7158/A also provide Power-On-Reset (POR) function and over-temperature protection. The Power-On-Reset circuit monitors supply voltages to prevent wrong operations. The over-temperature protection limits the junction temperature below 140 oC in case of short circuit or overload conditions
