P1110B

Overview

The P1110B is a wireless power receiver integrated circuit from Powercast Corporation, designed for the 915 MHz ISM band. It features an integrated full-wave rectifier and a linear low-dropout (LDO) regulator to provide stable output voltage. The device supports input voltages up to 24V and delivers regulated output currents suitable for powering IoT sensors and wearables. Key specifications include a maximum input power of 1W, an operating frequency range centered at 915MHz, and compliance with FCC Part 15 regulations for unlicensed operation.

Feature Summary

• Integrated RF-to-DC conversion with full-wave rectification
• On-chip linear regulator for stable output voltage
• Optimized for 915 MHz ISM band wireless power transfer
• Supports high-efficiency power delivery for low-power applications

Applications

• Wireless charging for Internet of Things (IoT) sensors
• Powering wearable electronic devices
• Battery-free sensor nodes in industrial monitoring
• Smart home automation components

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package type and tape-and-reel specifications match design requirements. Ensure regulatory compliance documentation aligns with target market standards. Cross-reference datasheet revisions for updated electrical characteristics and application notes prior to integration.

Selection Notes

Select the P1110B when designing systems requiring efficient 915 MHz wireless power reception. Consider its integrated LDO for simplified biasing needs. Evaluate coil coupling efficiency and distance constraints relative to the 1W input limit. Compare against other receivers if higher output current or different frequency bands are required.

Part Context

Part of Powercast's P-series wireless power receiver family, the P1110B complements transmitters like the P1020. It enables contactless energy transfer in compact form factors. The series targets mass-market IoT deployments where battery replacement is impractical. Integration with Powercast's ecosystem ensures interoperability and standardized testing protocols.

Replacement Considerations

No direct public substitute part numbers are confirmed. Alternative solutions may involve discrete rectifier and regulator combinations or competing ICs from vendors like Texas Instruments or NXP, though system-level redesign would be necessary.
