is safeguards are different sides of the battery charger that has been made and tempo. Series uses the concept of temperature protection that is in charge batteries, so batteries will not explode or burn because of excessive over-charge. Circuit by a temperature sensor of the NTC and an Op-Amp is set as the comparator voltage. Power regulator rangakain Battery Charger With Temperature Protection uses a transistor TIP32. Series Battery Charger With Temperature Protection is working with the source voltage 5VDC. The full series is as follows.
Battery Charger With Temperature Protection Circuit
Op-Amp used is ICLM393. Op-Amp Battery Charger circuits Z1a With Temperature Protection serves as a comparator between the voltage reference voltage (Vref) and the voltage of the battery temperature changes (Vtmp). The working principle of a series Battery Charger Temperature Protection With this, namely when the battery temperature is in charge has been increased and reached the appropriate temperature setting terentu the base bias voltage to the charger at the end so that the charge process is stopped. Op-amp Z1b same as Op-Amp Z1a, the voltage difference between the results of comparison are used to control LED flame. Voltage source for the series Battery Charger With Temperature Protection is 5VDC.
