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.
