Descriptions

NT1742 is an accurate secondary battery protection

IC for 2/3/4-cell Lithium-Lon/Lithium-Polymer battery

packs, on which a precise voltage detection circuit

with a specific reference is embedded.

NT1742 monitors individual cell voltages. If any cell

voltage reaches or goes over the specified voltage

and lasts for a period longer than the delay time set,

NT1742 activates an external MOSFET to blow the

three-terminal protection fuse, permanently disabling

the battery pack.

NT1742 has a CTL pin to control the output voltage of

the CO pin. The CTL pin can also offer an

over-temperature protection via PTC thermistor. If the

thermistor temperature exceeds the over-temperature

threshold and lasts for a period longer than the delay

time, the output pin activates the external MOSFET to

blow external fuse.
