Battery charger ICs
Improve battery lifetime, runtime, and charge time using TI battery chargers with high power density, low quiescent current, and fast charge current.
Shrink your design and overall solution size with a broad portfolio of power-dense battery charger ICs that support any input source and any charging topology (buck, buck-boost, boost and linear). Our chargers come with multiple low-power modes to help maximize battery runtime and stand-by time for the maximum charge and a battery that’s instantly ready for use.
