Li-Ion Battery Charger Circuit Using IC 555

The following post explains a straightforward yet precise Li-Ion battery charger circuit using the ubiquitous IC 555.A Li-ion battery as we all know needs to be charged under controlled conditions, if it's charged with ordinary means could lead to damage or even explosion of the battery.Basically Li-ion batteries don't like over charging their cells. Once the cells reach the upper threshold, the charging voltage should be cut off.The following Li-Ion battery charger circuit very efficiently f...

The operation of a MOSFET can be separated into three different modes, depending on the voltages at the terminals. In the following discussion, a simplified algebraic model is used.[9] Modern MOSFET characteristics are more complex than the algebraic model presented here For an enhancement-mode, n-channel MOSFET, the three operational modes are: Cutoff, subthreshold, or weak-inversion mode When VGS < Vth: where V G S is gate-to-source bias and V t h is the Threshold Voltage of the device.


Schmitt triggers are comparators with hysteresis. Their main feature is to ignore high frequency noise in their threshold voltage. The amount of positive feedback defined by the Ratio of the resistances (shown above as Rx 1 and Rx 10) latches the output until the opposite threshold is exceeded

How to keep SYMBOL MC9000 Series Scanner Battery live a productive life 1. Charge and discharge - For lithium ion batteries, you do not need to discharge them fully and recharge constantly. You need to do a full discharge only about every 30 charges. Do not charged to higher voltages than its threshold voltage. 2. Scanner Battery Storage - Store your SYMBOL MC9000 Series Battery in a clean, dry, cool place away from heat and metal objects.
