Linear Single Cell Li-Ion Battery Charger with Input Over

Voltage Protection

General Description

The RT9526A is a fully integrated low cost single cell Li-

ion battery charger ideal for portable applications. The

RT9526A is capable of being powered up from AC adapter

and USB (Universal Serial Bus) port inputs. The RT9526A

enters sleep mode when supplies are removed. The

RT9526A optimizes the charging task by using a control

algorithm including preconditioning mode, fast charge

mode, and constant voltage mode. The charging task will

remain in constant voltage mode to hold the battery in a

full charge condition. The charge current can be

programmed with an external resistor. The internal thermal

feedback circuitry regulates the die temperature to optimize

the charge rate under all ambient temperatures. The

RT9526A features 28V maximum rating voltage for VIN.

The other features are under voltage protection and over

voltage protection for the AC adapter supply.

The RT9526A is available in WDFN-8L 2x3 package to

achieve best solution for PCB space and total BOM cost

saving considerations.
