Description
Circuit schematic like in Figure 1 above is Circuit Schematic NiMH NiCd Battery Charger with Automatic Cuts Off using AN4558 IC. Eleccircuit site describe that if you need a NiMH NiCd battery charger circuit that automatic cuts off. The circuit uses IC-AN4558 or LM1458 OP-AMP, to detect a battery voltage. And, it will cut off fast the battery when the power is full. It is a simple project, and low cost to save your budget.
In the circuit diagram, as Figure 1 this circuit, we use a DC power supply 6 volts to 9 VDC. Secondly, they are applied to input point diode-D1 and capacitor-C1, which is filtered current to smooth up.
Then, IC1 is an OP-Amp is connected to a voltage comparator circuit. When we apply the battery to charging. During the first, the voltage across both battery less than 2.5 VDC, Which a positive will connects with pin 2 of IC1 so cause the voltage at pin 2 less than pin 3 of IC1. The voltage at pin 3 of IC1 will be adjusted at 2.6-2.8 VDC by a potentiometer-VR1. The output voltage at pin 1 of IC1 will have voltage is positive, LED2 glow and transistor -Q1 on can conduct current to the battery.
While the battery is charged, LED1 will do not grow. The circuit will still this states until the fully charged. And now you can read more you knowledge about Circuit Schematic NiMH NiCd Battery Charger with Automatic Cuts Off using AN4558 IC from the original source article using link [here].
