产品详细介绍
se9016 is a complete constant-current & constant voltage linear
charger for single cell lithium-ion and lithium-polymer batteries.
its sot-23 package and low external component count make se9016
ideally suited for portable applications. furthermore, the se9016
is specifically designed to work within usb power specification. at
the same time, se9016 can also be used in the standalone
lithium-ion and lithium-polymer battery chargers.
no external sense resistor is needed, and no blocking diode is
required due to the internal mosfet architecture. thermal feedback
regulates the charge current to limit the die temperature during
high power operation or high
ambient temperature. the charge voltage is fixed at 4.2v, and the
charge current can be programmed externally with a single resistor.
the se9016 automatically terminates the charge cycle when the
charge current drops to 1/10th the programmed value after the final
float voltage is reached.
when the input supply (wall adapter or usb supply) is removed, the
se9016 automatically enters a low current stage, dropping the
battery drain current to less than 2ua. the se9016 can be put into
shutdown mode, reducing the supply
current to 20ua.
other features include charge current monitor, undervoltage
lockout, automatic recharge and a status pin to indicate charge
termination and the presence of an input voltage. se9016 is
intentionally designed to have slightly negative
tempco. this provides extra protection to lithium battery during
charging.
