Specifications of any and all SANYO products described or contained herein stipulate the performance,

characteristics, and functions of the described products in the independent state, and are not guarantees

of the performance, characteristics, and functions of the described products as mounted in the customer's

products or equipment. To verify symptoms and states that cannot be evaluated in an independent device,

the customer should always evaluate and test devices mounted in the customer's products or equipment.

SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all

semiconductor products fail with some probability. It is possible that these probabilistic failures could

give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,

or that could cause damage to other property. When designing equipment, adopt safety measures so

that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective

circuits and error prevention circuits for safe design, redundant design, and structural design.

In the event that any or all SANYO products(including technical data,services) described or

contained herein are controlled under any of applicable local export control laws and regulations,

such products must not be expor ted without obtaining the expor t license from the author ities

concerned in accordance with the above law.

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 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 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 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.
