Voltage Protection
General Description
The RT9526A is a fully integrated low cost single cell Liion 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.
