The CN3052A is a complete constant-current /constant voltage linear charger for single cell Li-ion and Li Polymer rechargeable batteries. The device contains an on-chip power MOSFET and eliminates the need for the external sense resistor and blocking diode.
Abstract: It is critically important that lithium-ion battery stacks have a good battery-management system for monitoring many cellvoltages and cell temperatures. Without that monitoring, thermal runaway can lead to a battery explosion. This design idea presentsa low-power circuit that me ...
Smart Batteries are an increasingly popular choice formore than just traditional compact consumer electronicdevices. For example, Smart Batteries are being used asbattery backup for products such as blade servers, whereknowing battery status is very important
