The BQ24012DRCR is a linear charger for single-cell Lithium Ion or Lithium Polymer packs, terminating at 4.2V. Charge current is programmable up to 1A — set with a single resistor. Built-in short-circuit protection and a programmable timer guard against fault conditions. The constant-current / constant-voltage profile is standard for Li-Ion; the timer provides a backup termination if the current taper does not complete within the set window.
The maximum charge current is 1A, programmable via an external resistor. The charger operates in constant-current mode until the battery reaches 4.2V, then tapers to constant-voltage termination.
Yes, the charger supports both Lithium Ion and Lithium Polymer chemistries. The termination voltage is fixed at 4.2V, which is standard for single-cell Li-Polymer cells.
