Sample Application Circuit
Another Sample Application Circuit (solenoid drive)
Operation Description
1. The output power MOSFET will be turned on when the input voltage exceeds the input threshold voltage
2. The internal overcurrent protection function shuts down the output power MOSFET when output current of at least the
3. Shutdown state will be kept after overheat and overcurrent protections operation and the system will be reset when the
4. As an example of application circuit, DC voltage can also be controlled as a solenoid drive.

(5V 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.
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 165˚C (typical).
input voltage goes to or below the reset voltage (1.0V).
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).
