The new products can switch power sources through external signals and also through a built-in auto selection mode function, which switches sources automatically according to priorities programmed in advance.
Over voltage lock out (OVLO), reverse current blocking and other protection features used in safety designs are built-in, and will contribute to creating safer and more reliable power source switching solutions.
- Charging circuits of mobile devices including smartphones, tablets and wearable devices.
- Electronic devices with dual-input power supply systems, such as AC adapters and USB.
- Output current (max): 2A
- Input voltage (max): 36V
- Built-in protection features: Reverse current blocking circuit, thermal shutdown circuit, etc.
- Small package size: 0.5mm pitch, 1.9 x 1.9mm WCSP type package
|Part Number||Package||VIN (max)||IOUT (max)||Input Priority||Auto Selection Mode||
OVLO Level (typ.)
|Monitored Input||Active Indication Level|
|TCK321G||WCSP16C (1919)||36V||2A||VIN A||Built-in||12.0V||VIN A||Low|
 In the auto selection mode, input and output of the A-side power source is prioritized. However, when there is no power supplied to the A-side, input and output of the B-side power source is used.
 The main switch is turned off to protect the system, when excess voltage exceeding a fixed OVLO level is detected.
