However, uc390 the transmitter is keyed increasing the current demandthe charger can’t supply the required current, so it’s taken from the battery and the battery voltage begins to drop. Mar 30, 5: You can use the design procedure on page 5 in the datasheet. The maximum bulk-charge rate is set by the value of R3 in the series regulator circuit. R11, R12 and R13 function as a voltage divider to supply a portion of the battery voltage to pin 2 of U4A.

As the battery continues to charge, the pulses get narrower and the time between pulses increases a lower duty cycle. Mar 30, 3: Due to the special circuit structure is simple charger while maintaining optimal performance.
Hope can get the reply as soon uc39006 poosible.
Intelligent 1Ah – 55Ah Battery Charger Circuit UC3906
U4B’s output remains at 12 V until C5 has charged through R6 approximately four seconds and the trigger has been released by U4A sensing the battery dropping to It is very important that this charger be connected directly to the SLA battery with no diodes, resistors or other electronics in u3906 the two. If the voltage is still above Because the repetition rate is very low a maximum of one current pulse every four seconds no RFI is generated that could be picked up by the K2 receiver.
When ac power is applied but U1 is switched off and not supplying current to the battery, D3 glows red. Use of the information on this site may require a license from a third party, or a license from TI. Can you tell me what the battery voltage is at this time? When the current has been off for four seconds, the charger reads the battery voltage.
An automatic sealed-lead-acid battery charger
Remove the test voltage and ac power and install the jumper at J 1. Under this condition, oxygen and hydrogen are generated faster than they can be recombined, u3c906 pressure inside the battery increases. Internally, the circuit is set to three modes of charging. Comments What type of Lead Acid is this designed for?
I had see the datasheet for few times already.
The LMT used here is rated for a maximum current of 1. Note that the mounting tab on U1 is not at ground potential. Then compare that to the pin 10 of the charger, you will have a better understanding on what is uc3096 on in the ic3906.
The comments pertaining to the SLA batteries and chargers apply across the board and the charger described here can be used with any similar battery.
SLAs are uc906 called gel-cells because of their gelled electrolyte. If we unkey the transmitter before the battery voltage reaches This question is for testing whether you are a human visitor and to prevent automated spam submissions.

As the battery charges, its voltage begins to climb.
