All our power management IC's includes an on-chip battery protect circuit designed for direct connection to unprotected Li-Ion / Li-Polymer battery cells. These line of power management IC's offers OEMs a convenient and cost saving migration for existing non-rechargeable battery-powered products to be converted as rechargeable.

     By providing this feature on-chip, the overall circuit will require very few external components which makes it possible to include a complete battery charger with protect circuit, and an unprotected Li-Ion / Li-Polymer battery entirely on the product PCB thus eliminating additional tooling for existing product enclosures and permitting their use with minimal revision. For the product end-user, it offers the convenience of having a product rechargeable via the USB port, making it lightweight, safe, plus the added savings on new battery purchases.

     Moreover, all of our Power Management IC's incorporate a safe algorithm integrated with safety timers for charging via the USB port, single cell Li-Ion / Li-Polymer batteries thus ensuring full protection against the hazards of overcharging.
