CXPR7162 CXPR7162A提供完整的锂+充电器保护，防止输入过电压、输入过电流和过热。当监测到的任何参数超过阈值时，IC关闭充电电流。所有保护装置也有防电压尖峰或电流瞬变引起误触发的脱胶时间。当ACIN电压超过OVP阈值时，设备将关闭充电电流。充电电流由GATDRV引脚控制。当从GATDRV管脚提供电流时，输出管脚提供的充电电流是GATDRV电流放大200倍的幅度。其他功能包括精确的VVCTT/VACIN分压器、从OUT到ACIN的反向电流阻断和OTP保护。L3216提供完整的Li+充电器保护，可以为手机PMIC的充电器节省外部组件。以上特点和小包装使CXPR7162成为手机应用的理想部件。

产品概述 返回TOP
The CXPR7162 provides complete Li+ charger protection against Input over-voltage, input over-current and overtemperature. 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. When ACIN voltage exceeds OVP threshold, the device will turn off charging current. The charging current is controlled by the GATDRV pin. When sourcing a current from the GATDRV pin, the OUT pin delivers the charging current which is 200-fold magnified in amplitude based on GATDRV’s current. Other features include accurate VVCDT/VACIN Voltage divider, reverse current blocking from OUT to ACIN and OTP protection. The CXPR7162 provides complete Li+ charger protections, that can save the external components for the charger of cell phone’s PMIC. The above features and small package make the CXPR7162 an ideal part for cell phones applications.
