voltage, if VIN exceeds the threshold voltage and
lasts longer than 100ns, the internal power
a P-MOSFET turned off, CHRIN pulled down.
i AW3210A Built-in current limiting protection circuit,
the charging current is limited to a safe range.
t AW3210A possesses the specific K-ChargeTM
technology, the output current can be adjusted
n smartly according to the chip temperature to
e ensure safety during the entire charging process.
fid AW3210A integrates the charging P-MOSFET,
eliminating the need for external charging
P-MOSFET and Schottky Diode among a phone
charging system. And the reverse current blocking
function has been designed in AW3210A, when the
CHRIN voltage drops below the OUT, charging
P-MOSFET turned off, preventing current draining
nfrom the lithium-ion battery into AW3210A.
oAW3210A is available in DFN 3×3-10L package.
