AUR9801D
LI-ION/LI POLYMER BATTERY CHARGER
Description
Pin Assignments
The AUR9801D is a highly-integrated battery charger for single-cell
Li-ion or Li-polymer batteries capable of operating with an input
voltage reached 2.5V. It is a complete charger device designed to
work with an USB port or 5V output AC adapter.

Pin 1 Mark
The AUR9801D operates with CC (constant current) mode and CV
(constant voltage) mode profiles. A low-current preconditioning
charge mode is also provided as a trickle charging operation. The
charge current is programmable up to 1A with an external resistor or
a logic input. The charge voltage is 0.6% accurate over the full
application range.
When operating with a current-limited adapter, the charger minimizes
the thermal dissipation with pulsed operations to prevent overheat
conditions that is commonly occurred with conventional linear
chargers. The AUR9801D reduces charge current for thermal fold-
back to ensure product safe operation. The charger automatically re-
charges the battery when the battery voltage drops below a recharge
threshold. The chip includes a safety timer for setting the fast charge
time limit in case of charging a dead battery.
Additional features include preconditioning of an over-discharged
battery and charging the battery in a safe temperature range with an
NTC thermistor interface. The thermally enhanced DFN package is
offered for space limited handheld applications.
