世微DW09 锂电池保护芯片 内置二合一

DESCRIPTION
The DW09
series product is a high
integration solution for lithium-ion/polymer battery
protection. DW09
contains advanced power
MOSFET, high-accuracy voltage detection circuits
and delay circuits. DW09
is put into a small
package and only one external component makes it
an ideal solution in limited space of battery pack.
DW09
has all the protection functions required in
the battery application including overcharging,
over-discharging, overcurrent and load short
circuiting protection etc. The accurate safe and full
utilization charging. The low standby current drains
little current from the cell while in storage. The
device is only targeted for digital cellular phones, but
also for any other Li-ion and Li-Poly
battery-powered information appliance requiring
long-term battery life.
