一,产品概述(General Description)         
     The JTM5418 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.

charging. This condition is called the overcharge voltage condition. If the error condition clears
within overcharge voltage detection delay time, no action will be taken.
The overcharge condition is released by the following two events:
(1) When the battery voltage drops below the overcharge release voltage (VCL), the
turns the charging control FET on and returns to the normal condition.
(2) When a load is connected and discharging starts, the JTM5418
