产品名称:单节锂电池保护
产品型号:HT4301
The HT4301 series product is a high integration
solution for lithium-ion/polymer battery protection.
HT4301 contains advanced power MOSFET,
high-accuracy voltage detection circuits and delay
circuits. HT4301 is put into an ultra-small
SOT23-5 package and only one external
component makes it an ideal solution in limited
space of battery pack.
HT4301 has all the protection functions required
in the battery application including overcharging,
overdischarging, overcurrent and load short
circuiting protection etc. The accurate
overcharging detection voltage ensures safe and
full utilization charging. The low standby current
drains little current from the cell while in storage.
The device is not only targeted for digital cellular
phones, but also for any other Li-Ion and Li-Poly
battery-powered information appliances requiring
long-term battery life.
