6 FAQs about [Battery charge and discharge chip]

How does a battery discharge work?

If a battery discharge is requested, a discharge cycle is started fol-lowed by a complete charging cycle. The microcontroller also monitors the current source (when charging through an I/O line) and a current sense resistor to provide constant current to the battery.

How can microchip's Li-ion battery charge management controllers help you?

This application note shows how to take advantage of Microchip’s fully integrated simple Li-Ion battery charge management controllers with common directional control to build a system and battery load sharing circuitry. The solutions are ideal for use in cost-sensi-tive applications that can also accelerate the product time-to-market rate.

What is a battery charger IC?

What happens when a battery is discharged?

When a multi-cell series-connected battery is dis-charged, the lowest capacity cell will reach the point of full discharge before the other cells. If discharge is con-tinued, the lower capacity cell can be driven into an overdischarge condition through 0.0V. This will cause its polarity to reverse.

What is included in a battery protection chip?

Also included are stand-alone high voltage battery protection circuitry, a voltage regulator capable of running the chip on a supply varying from 4 to 25 Volts, integrated cell balancing FETs, and special high voltage I/O capable of controlling charge and discharge.

Should a NiCd battery be fully discharged?

Periodic full (deep) discharge is sufficient to reduce memory effect. Therefore, it is not necessary to fully discharge a NiCd battery each time. A reversible drop in voltage and capacity may occur when a sealed NiMH battery is partially discharged and then recharged. This results in voltage depression or the “memory effect.”
