BQ24296RGET SMD LED Chip Battery Chargers IC Lithium Ion/Polymer 24-VQFN
Charger IC Lithium Ion/Polymer 24-VQFN (4x4) IC BATT CHG LI-ION 1CELL
Its low impedance power path optimizes switch-mode operation efficiency, reduces battery charge time and
extends battery life during discharging phase. The I2C serial interface with charging and system settings makes
the device a truly flexible solution.
