Overview
® RT9536H Linear Single Cell Li-Ion Battery Charger IC for Portable Applications General Description The RT9536H is a fully integrated single cell Li-ion battery charger IC ideal for portable applications.
The RT9536H optimizes the charging task by using a control algorithm including pre-charge mode, fast charge mode and constant voltage mode.
The input voltage range of the VIN pin can be as high as 28V.
When the input voltage exceeds the OVP threshold, it will turn off the charging MOSFET to avoid overheating of the chip.
In RT9536H, the maximum charging current can be programmed with an external resistor.
For USB application, the user can set the current to 100mA/500mA through the EN/SET pin.
For the factory mode, the RT9536H can allow 4.
25V or 4.
4V/2.
3A power pass through to support system operation.
It also provides a 50mA LDO to support the power of peripheral circuit.
The internal thermal feedback circuit regulates the die temperature to optimize the charge rate for all ambient temperatures.
The RT9536H provides protection functions such as under voltage protection, over voltage protection for VIN supply and thermal protection for battery temperature.
The RT9536H is available in a WDFN-10L 3x2 package to achieve optimized solution for PCB space and thermal considerations.
