Overview
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 VCC. 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 (TJ) from –40°C to +125°C.
