Single lithium battery protection board polymer battery protection board 3.7v

 Product description single lithium battery protection board polymer battery protection board 3.7v new lower single string configuration designed for lithium-polymer battery protection board design large favorably greater the amount of the price, to accept wholesale, style telephone 15108399357? Performance Specification Typical operating current 2-3A current continues to consume a single cell (self-consumption) ≤6uA Maximum continuous discharge current of 3A overcharge protection Overcharge detection voltage 4.25 V ± 0.025V overcharge detection delay time 150-500 ms overcharge recovery Voltage 4.0V ± 0.025V over-discharge protection over-discharge detection voltage 2.5.00V ± 0.1V Over discharge detection delay time 50-150ms discharge recovery voltage 3.0V ± 0.10V overcurrent protection overcurrent detection voltage 0.08V overcurrent detection current Detection delay time 5ms-15ms recovery state over 3A-4A automatic recovery Short circuit protection detection state of the external short-circuiting detection delay time ≤50us restore state auto-recovery Resistance Protection circuitry (MOSPET) ≤60mΩ Temperature Operating temperature range -40 to + 50 ℃ storage temperature range of -40 ~ + 90 ℃ the latest version PCB. Chip protection board adopted the use of higher-priced Taiwan Fu Jing and the Japanese Seiko IC IC chip original, non-domestic chip, domestic chip high failure rate, we do not use this inexpensive chip. ? Overview: ??? main IC uses the original "Fu Jing and Seiko" imported components. Overcharge, over discharge, over current, short circuit protection, for a variety of capacities in various shapes 3.7V lithium batteries. Seiko Japan and Taiwan Fu Jing protection of IC, VISHAY, AOS, IR and other high-quality MOSFET, FR-4. Low temperature coefficient of the plate, design, fine workmanship, a comprehensive test; compact, suitable for applications demanding high-integration, low cost applications meet a wide range performance requirements, to ensure the absolute safety and reliability of the battery pack. ? First make sure that the parameters before using the charger meets the requirements of your equipment we produce Charger Products:? Welcome to obtain samples and quotations. ???????????????????? ??
