TPK1031L1-VS1R Power Sequencer IC – Multi-Channel Rail Control
The TPK1031L1-VS1R is a multi-channel power sequencer IC used to gate and time the rail-up sequence of complex digital systems — including ASIC miner hashboards and control boards that demand strict power-on order across multiple DC rails (core, IO, PHY, memory) to avoid latch-up or undefined chip state.
Stocking part for repair shops rebuilding power-management subsystems on hashboards + CBs where the original sequencer has failed. Configurable enable timing via external R/C network around the IC.
Typical Use Cases
- Hashboard PMIC rebuild — restore multi-rail sequencing on damaged boards.
- Control-board power-up logic — gate core + IO + PHY rails in order.
- System-level fault diagnosis — verify sequencer behaviour after repair.
- Bench stock — drop-in replacement for damaged sequencers.

FAQ — TPK1031L1 Power Sequencer
Q: How does this differ from a simple soft-start?
A: Sequencer controls timing + order across multiple independent rails. Soft-start controls slew on a single rail. Multi-rail systems need sequencers.
Q: Which hashboards use this part?
A: Used on various ASIC miner PMIC sub-circuits. Confirm against your board's part number before ordering.
Q: Bulk pricing?
A: Yes — email contact@lys-sz.com.
