Description

The TPK1032 series of products is a simple power sequencer, which provides power-up and power-down sequence control of multi-channel power supplies. Furthermore, the TPK1032 series supports a maximum of three devices cascaded to control the sequence of nine- channel power rails in one system. The TPK1032 series of products has three open-drain output channels, and all the channels can be pulled up to any required voltage level equal to or lower than V CC. When the TPK1032 series is enabled and the EN pin goes high, the three output channels turn to high with the sequence of FLAG1-FLAG2-FLAG3 after the selected delay period individually. When the TPK1032 series is disabled and the EN pin goes low, the three output channels turn low one by one with the selected sequence after the selected delay period individually. The TPK1032 series of products provides a SOT23-6 package with a guaranteed junction temperature range (TJ) from −40°C to +125°C.

  • The FLAGx pull-up resistors, recommended 100 kΩ, should be placed close to the flag output pins and the pull-up power supply. The traces should be equal to each other, and the trace length should be as short as possible. TPK1032 Series 3-Channel Simple Power Sequencer www.3peak.com 14 / 18 GA20240603A2
