Operation Description
•
The 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 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 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
turning off the current of output power MOSFET when Tj comes to 150°C (typical).
•
As an example of application circuit, DC voltage can also be controlled as a solenoid drive.
Addition
•
The diode between OUT and GND in the block diagram is parasitic diode of the MOSFET.
•
Not apply a voltage on IN terminal during the period when OUT voltage is lower then GND voltage when driving
a solenoid or a motor.
•
Be sure connect a diode between OUT terminal and GND terminal when you want to apply a voltage on IN terminal
under the above-stated state (that is, OUT Voltage < GND Voltage).
