TS12001-C021DFNR

Overview

The TS12001-C021DFNR is a NanoSmart Switch battery management IC from Semtech. It features an ultra-low quiescent current of 100 pA and operates with a 4V threshold. The device supports a supply voltage range of 1.2 V to 5.5 V and draws only 70 nA in operating mode. It is housed in an 8-lead DFN package suitable for surface mount installation. The component functions as a charge management solution designed for high-efficiency power control in compact electronic systems.

Feature Summary

• Ultra-low leakage current capability for extended standby performance
• Integrated charge management functionality within a compact footprint
• Wide input voltage tolerance for flexible system integration

Applications

• Battery-powered portable electronics
• IoT sensor nodes requiring minimal standby drain
• Wearable health monitoring devices

Procurement Notes

Verify the specific suffix DFNR against official Semtech documentation to confirm package type and tape-and-reel specifications. Ensure the 4V threshold aligns with your battery chemistry requirements. Cross-reference the part number with authorized distributors to confirm availability status, as inventory levels fluctuate. Confirm RoHS compliance and lead-free status through the manufacturer's latest datasheet before finalizing procurement orders.

Selection Notes

Select this component when ultra-low quiescent current is critical for maximizing battery life in low-duty-cycle applications. The 1.2 V to 5.5 V operating range allows compatibility with various single-cell battery configurations. Consider the DFN-8 package size if board space is constrained. Evaluate the 70 nA active current consumption against total system power budgets to ensure it meets efficiency targets compared to higher-current alternatives.

Part Context

This part belongs to Semtech's NanoSmart Switch series, focusing on precision power management for energy-constrained environments. The TS12001 series emphasizes minimizing self-discharge and leakage to preserve stored energy in batteries. It complements Semtech's broader portfolio of IoT and signal integrity solutions by addressing the fundamental power distribution needs at the edge node level.

Replacement Considerations

Check Semtech's official cross-reference guides for direct replacements. Verify that any substitute maintains the 100 pA leakage specification and 4V threshold. Ensure the replacement package matches the DFN-8 footprint to avoid PCB redesign.
