Description

The TP3219J is an electronic component in the IC Chips product category. It is a protection IC designed for over-charge/discharge of rechargeable one-cell Lithium-ion (Li+) batteries. This IC is manufactured using the CMOS process. It can detect over-charge/discharge of Li+ one-cell and excess load current. Additionally, it includes a short circuit protector to prevent large external short circuit currents. The TP3219J consists of three voltage detectors, a reference unit, a hysteresis circuit, and a short circuit protector. When the charging voltage exceeds the detector threshold, the over-charge detector/VD1 switches to a low level. After detecting overcharge, the VD1 can be reset and the output of COUT pin becomes "H" when the VDD voltage decreases below a certain level, or when a charger is disconnected from the battery pack while the VDD level is between specific thresholds in the TP3219J version.
