It accepts a 5V–28V supply and delivers CC/CV charging with a termination voltage set for supercap stacks, not cells. The 1 mA supply current keeps quiescent draw negligible in always-on backup systems. ## Package and procurement posture Supplied in Tape & Reel (TR) or Cut Tape (CT) in a 16-VQFN (3.5x3.5) package.
