TPK1032AEL1-S6TR

This series is a simple power sequencer that provides power-up and power-down sequencing control for multi-channel power supplies. In addition, the series supports cascading up to three devices to control the sequencing of nine power rails in a single system. The series features three open-drain output channels, all of which can be pulled up to any desired voltage level equal to or lower than VCC. When the series is enabled and the EN pin goes high, the three output channels go high in the order FLAG1-FLAG2-FLAG3, each after its respective selected delay period. When the series is disabled and the EN pin goes low, the three output channels go low one by one in the selected order, each after its respective selected delay period. The series is offered in a SOT23-6 package with a guaranteed junction temperature range of -40°C to +125°C.
