功能特点

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.
