6V max supply, multi-chemistry charge controller in 8-SOIC
The Texas Instruments BQ24401DR is a multi-chemistry battery charge controller in an 8-SOIC surface-mount package, designed for applications requiring a programmable charge termination timer and a 6V maximum supply rail.
Programmable timer and supply rail limits
The programmable timer feature allows the charge termination timeout to be set externally, giving the designer control over the charge cycle duration independent of the battery chemistry. The 6V maximum supply voltage means the input rail must be regulated to stay below that ceiling — a 5V USB bus or a 5.5V wall wart fits; a 12V lead-acid rail needs a pre-regulator.
