Hot Swap Controllers datasheet and documents for TPS2321IDR
Hot Swap Controllers Overview
The TPS2321IDR is a dual hot swap power controller manufactured by Texas Instruments, designed for safe insertion and removal of live circuit boards. It operates within a supply voltage range of 3 V to 13 V and features two independent channels with integrated circuit breaker functionality. The device supports a maximum operating temperature of +85°C and draws a typical quiescent current of 200 µA. Packaged in a 16-pin SOIC (Narrow) surface-mount case, it provides robust protection against overcurrent and thermal events during system maintenance.
Hot Swap Controllers Feature Summary
- Dual-channel architecture with independent control for separate load management
- Integrated circuit breaker capability for automatic fault isolation
- Supports hot swapping of live circuits without system disruption
Hot Swap Controllers Applications
- Server blade insertion and removal systems
- Telecommunications equipment backplanes
- Industrial control modules requiring live maintenance
Hot Swap Controllers Procurement Notes
Verify the specific suffix 'IDR' indicates tape-and-reel packaging versus the 'ID' tube variant. Confirm RoHS compliance status through official datasheets. Ensure the 16-SOIC package dimensions match your PCB footprint requirements. Check for any recent lifecycle notices regarding obsolescence or alternative recommendations from Texas Instruments.
Hot Swap Controllers Selection Notes
Select this component when dual independent hot swap protection is required within a 3V to 13V input range. Consider the 200 µA quiescent current for low-power standby applications. The SOIC-16 package suits space-constrained designs needing surface-mount assembly. Verify thermal performance meets your board's heat dissipation capabilities under full load conditions.
Hot Swap Controllers Part Context
This part belongs to the TPS2321 family of dual hot swap controllers. It complements other Texas Instruments power management solutions by providing precise current limiting and soft-start features. The device is distinct from RS-232 interface ICs like the MAX232ID, serving purely as a power distribution protector rather than a communication transceiver.
Hot Swap Controllers Replacement Considerations
Consult Texas Instruments documentation for direct pin-compatible alternatives. Verify that substitute parts maintain identical dual-channel functionality and 13V maximum rating. Ensure replacement components support the same SOIC-16 package and thermal characteristics.
