The TND012NM output power MOSFET will be turned on when the input voltage exceeds the input threshold voltage (4 to 6V is recommended), and then the lamp will be turned on by the current flowing to the lamp. Conversely, the output power MOSFET will be turned off when the input voltage goes below the input threshold voltage, and then the lamp will be turned off.
The inrush current that occurs during normal lamp operation is limited to a preset value by the built-in overcurrent protecting circuit, which makes the lamp life longer. The internal overcurrent protection function of TND012NM limits the current of output power MOSFET when output current of at least the overcurrent detecting current value flows at load short. Besides, if the device temperature exceeds the allowable power dissipation, overheat protection function protects the power switch from being broken down by shutting down the MOSFET when Tj comes to 150°C (typical).
Shutdown state will be kept after overheat protection operation and the TND012NM system will be reset when the input voltage goes to or below the reset voltage (1V).
As an example of application circuit, DC voltage can also be controlled as a solenoid drive.
