Description

The TPK1031 series products are simple power sequencers,

which provide power-up and power-down sequence control of

multi-channel power supplies. Furthermore, the TPK1031 series

support maximum three devices cascaded to control sequence

of nine-channel power rails in one system.

The TPK1031 series products have three open-drain output

channels, and all the channels can be pulled up to any required

voltage level equal or lower than V

. When the TPK1031 series

are enabled with EN pin goes high, the three output channels

toggle with the sequence of FLAG1-FLAG2-FLAG3 after the

delay period individually set by the external capacitor; when the

TPK1031 series are disabled with EN pin goes low, the three

output channels toggle following a reverse sequence after the

delay period individually set by the external capacitor.

The TPK1031 series products provide small MSOP-8 package

with guaranteed junction temperature range (T

) from –40°C to

+125°C.
