Product details

Single-cell Li-Ion linear charger at 1.2A

The charge current and charge timer are programmable via external components, giving the designer control over the charge profile without an I2C bus. Built-in over-temperature fault protection shuts down the charger if the die temperature exceeds the safe limit, protecting both the IC and the battery during fault conditions.

Package and thermal design for 20-VQFN

Maximum supply voltage is 10V, and the battery regulation voltage is 4.2V — the charger regulates the battery voltage to this level at the end of the constant-current/constant-voltage cycle.

Frequently asked questions

What is the charging current of BQ24001RGWR?

The maximum charge current is 1.2A, and it is programmable via an external resistor. The charger operates in constant-current mode during the bulk charge phase.
