Electrical Characteristics (continued)

Notes:

(1) Electrical Characteristics apply for V

VIN

= 4.75V to 5.25V, but are tested only at V

VIN

= 5.00V, unless noted.

(2) Pre-charge threshold is applied directly at VOUT for any setting of V

CV

, whether 4.1V or 4.2V fixed, or Adjust Mode.

(3) Re-charge threshold is relative to V

CV

as measured at BSEN. For either of the fixed output voltage settings, V

BSEN

is compared directly to

the programmed CV regulation voltage. In Adjust Mode, V

BSEN

is compared to the Adjust Mode feedback voltage, V

ADJMF

. So the re-charge

threshold at the battery is VT

ReQ

× V

CV

/ V
