TPS2320IPWG4

Hot Swap Controllers Overview

The TPS2320IPWG4 is a dual-channel hot-swap voltage controller manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 13 V and supports two independent channels for power management. The device features an operating quiescent current of 200 uA and 1 mA, ensuring efficient power usage during standby and active states. Designed for surface-mount applications, it utilizes a TSSOP-16 package. The component functions reliably across an extended temperature range from -40 °C to +85 °C, making it suitable for industrial environments requiring robust power sequencing and protection.

Hot Swap Controllers Feature Summary

• Dual-channel architecture with independent circuit breaking capabilities for separate load management
• Integrated inrush current limiting to prevent bus collapse during system startup
• Programmable fault timeout and undervoltage lockout (UVLO) for enhanced system reliability

Hot Swap Controllers Applications

• Hot-swap insertion in backplane systems
• Power distribution units requiring controlled ramp-up
• Industrial equipment with redundant power supplies

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm RoHS compliance status and lead-free material specifications. Ensure the TSSOP-16 package variant matches the design requirements. Cross-reference the part number with the latest datasheet revision to confirm availability and any potential obsolescence notices prior to procurement.

Hot Swap Controllers Selection Notes

Select this component when dual independent channel control is required for hot-swap applications. The wide input voltage range accommodates various system rails. Consider the TSSOP-16 footprint for space-constrained designs. Verify that the programmable thresholds meet the specific inrush and fault protection requirements of the target application without external components.

Hot Swap Controllers Part Context

This part belongs to the TPS2320 series of hot-swap controllers. It is a lead-free, RoHS-compliant version of the standard TPS2320IPW. The series provides integrated protection for high-density power distribution systems. It serves as a specialized power management IC within the broader PMIC category, focusing on safe insertion and removal of live circuits.

Hot Swap Controllers Replacement Considerations

The TPS2320IDR offers a SOIC-Narrow-16 package alternative with similar electrical characteristics. The TPS2320IPW is the non-RoHS compliant tube version of the same functional device. Verify pin compatibility and thermal performance when substituting between package types.
