ISPPAC30-01PI

Overview

The ISPPAC30-01PI is a programmable power management integrated circuit manufactured by Lattice Semiconductor. It integrates board-level power management functions, including voltage monitoring, sequencing, and reset generation, into a single CPLD-based device. The component supports configuration and control via the Serial Peripheral Interface (SPI). It features up to 12 differential voltage sensors with noise immunity and includes on-chip DACs for margining and trimming. The device operates within a wide supply range of 3.3 V (+20% to -15%) and provides high-voltage MOSFET driver outputs.

Feature Summary

• Integrated power management with up to 12 differential voltage sensors
• SPI interface for configuration and control
• Up to 8 on-chip DACs for voltage margining and trimming
• Ruggedized CPLD core with up to 48 macrocells for logic

Applications

• Board input (primary) supply management
• Payload (secondary) power management
• -48V hot-swap applications
• +12V/+24V redundant supply selection

Procurement Notes

Verify the specific suffix '01PI' against the latest Lattice datasheet to confirm pinout and package details. Ensure compatibility with the PAC-Designer software for configuration uploads. Check for any Product Change Notifications (PCNs) regarding assembly suppliers or marking format changes that may affect integration.

Selection Notes

Select this component when board power management requires integrated sequencing, supervision, and SPI control in a compact form factor. It is suitable for designs needing precise voltage monitoring with noise immunity and hardware-level fault response without external discrete components for basic supervisory logic.

Part Context

The ISPPAC30 belongs to the Power Manager II family from Lattice Semiconductor. This family targets engineers seeking to reduce Bill of Materials (BOM) costs by integrating hot-swap controllers, power supply or'ing, and reset generation into a single ruggedized CPLD device.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other devices in the Power Manager II family if alternative sourcing is required.
