APPLICATIONS
GENERAL DESCRIPTION
The MT1430 is a battery protection solution
IC which is integrated with built-in the
protection IC to use a Lithium-ion/Polymer
batteries developed for one cell series. The
device contains all required protection
control
circuits
together
with
very-low-resistance MOSFETs to minimize
the number of external components. The
protection IC is composed of three voltage
detectors, over current, short detection
circuit, reference voltage sources, oscillator,
counter circuit and logical circuits.
The device is not only targeted for digital
cellular phones, but also for any other
Li-ion/pol battery powered information
appliances requiring long term battery life.
