TQL850CSV50

Taiwan Semiconductor

7

Version: A2206

APPLICATION INFORMATION (CONTINUE)

Enable

The EN pin is high voltage tolerant pin. High input enables the device ON and low is disable which can be

connected to microcontroller or digital control system. It can be connected to input power pin directly.

Thermal Shutdown (TSD)

Internal 160°C comparator will trigger temperature protection (TSD). TSD will shut down system, until internal

temperature back to 130°C.

Current Limit

The TQL850CSV50 features Current Limit function to protect device from damage by excessive power dissipation

such as OUT shorted to GND. It limits output current to maintain power dissipation in the safe region.
