Product Description

The BQ24202DGN is a Li-ion Charger targeted at low space and current limited charger applications. The BQ2420x series offer integrated powerFET, high-accuracy voltage regulation, temperature monitoring, charge status and charge termination, in a single monolithic device. It is designed to work with a current-limited wall-mount transformer and therefore does not provide any current regulation. However, these devices offer a fixed internal current limit to prevent damage to the internal powerFET. A time-limited pre-conditioning phase is provided to condition deeply discharged cells. Once the battery reaches the charge voltage, the high accuracy voltage regulation loop takes over and completes the charge cycle. Charge is terminated based on minimum current. An internal charge timer provides a backup safety for charge termination. Other standard features include an automatic sleep mode activated when VCC falls below the battery voltage falls below the VRCH threshold.
Integrated voltage regulation with 0.5% accuracy
Battery insertion and removal detection
Charge termination by minimum current and time
Pre-charge conditioning with safety timer
Sleep mode for low-power consumption
Charge status output for LED or host processor interface indicates
Charge-in-progress, charge completion and fault conditions
Optional temperature monitoring before and during charge
Green product and no Sb/Br
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
