Usage Notes

LA4917H

1. This IC includes power supply shorting (shorting between the power supply and the outputs) and ground shorting

(shorting between ground and the outputs) protection circuits. These circuits operate to protect the IC against abnormal

connections.

These circuits will continue to operate as long as the corresponding abnormal condition continues and recover

automatically when the abnormal condition is cleared.

2. This IC includes a thermal protection circuit that operates when the junction temperature (Tj) exceeds about 160°C.

This circuit gradually lowers (attenuates) the outputs.

3. If this IC is operated in the vicinity of its maximum ratings, small fluctuations in the operating conditions may cause

the maximum ratings to be exceeded and may lead to destruction of the IC. Therefore, designs must provide adequate

margins in the supply voltage and other parameters so that this IC will only be used within ranges such that the

maximum ratings are never exceeded.

Specifications of any and all SANYO Semiconductor 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 Semiconductor 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 Semiconductor 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 exported without obtaining the export license from the authorities concerned in

accordance with the above law.
