Load Switch IC TCK301G, TCK302G, TCK303G Application & Circuit
This reference design provides example circuit of the load switch with low on resistance and built-in in-rush current control function. It is suitable for battery used application.
Load Switch IC TCK301G, TCK302G, TCK303G Application & Circuit
Description
- Operation and application of the slew rate control circuitry designed for inrush current limiting
- Main switches of USB PD-enabled rapid-charging circuits for electronic devices with USB Type-C™ ports
- Main switches of 5- to 12-V power supply input circuits that support various modes of rapid charging and wireless power transfer
- Switches for the power management of systems requiring power-saving modes
Features
- Small package: 0.5 mm pitch WCSP9 ( 1.5 mm x 1.5 mm, t: 0.5 mm (Typ.)) , PD = 1.65 W
- High input voltage: VIN (Max) = 28 V
- High output current: IOUT (DC) = 3.0 A
- Low ON resistance : RON = 73 mΩ (Typ.) at VIN = 4.5 V, IOUT = - 1.0 A
- Inrush current reducing circuit ( slew rate control )
- Over voltage lockout circuit : 6.6 V at 301G, 10.5 V at 302G, and 15.5 V at 303G (Typ.)
- Under voltage lockout circuit: 2.9 V (Typ.)
