AC100V
Sample Application Circuit
Operation Description
1.The output power MOSFET will be turned on when the input voltage exceeds the input threshold voltage (5V is
2.The internal overcurrent protection function shuts down the output power MOSFET when output current of at
3.Shutdown state will be kept after overheat and overcurrent protections operation and the system will be reset
4.As an example of application circuit, DC voltage can also be controlled as a solenoid drive.
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.
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 165˚C (typical).
when the input voltage goes to or below the reset voltage (1.0V).
This catalog provides information as of January, 2001. Specifications and information herein are subject
to change without notice.
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 authorities
concerned in accordance with the above law.
