SP69 High Current Power Switch 2007 Sipex Corporation
Overtemperature Protection
The SP69 has built-in overtemperature
protection to protect the part against dam-
age if the die temperature gets too hot. The
typical thermal cutoff is about 50oC. The
part will self recover if the temperature drops
below the thermal restart threshold of about
20oC.
Layout Considerations
The input and output decoupling capacitors
should be placed as close as possible to the
input and output pins. The GND pin should
be stitched to the GND plain to help with
thermal performance. The input and output
traces should be as large as possible. The
100K is also recommended in the design
and should be placed close to the output de-
coupling cap.
