Overview
The TPK1031 is a series of simple power sequencers, providing power-up and power-down sequence control of multi-channel power supplies. Furthermore, the TPK1031 series supports a maximum of three devices cascaded to control the sequence of nine-channel power rails in one system.
The TPK1031 series has three open-drain output channels, and all the channels can be pulled up to any required voltage level equal to or lower than VCC. When the TPK1031 series is enabled and the EN pin goes high, the three output channels toggle with the sequence of FLAG1-FLAG2-FLAG3 after the delay period is individually set by the external capacitor. When the TPK1031 series is disabled and the EN pin goes low, the three output channels toggle following a reverse sequence after the delay period is individually set by the external capacitor.
The TPK1031 series provides a small MSOP8 package with a guaranteed junction temperature range (TJ) from −40°C to +125°C.
