TPS2331IDRG4

Hot Swap Controllers Overview

The TPS2331IDRG4 is a single-channel hot-swap voltage 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 programmable current limiting, fault timeout, and slew rate control. The device includes under-voltage lockout (UVLO) and latched fault protection mechanisms. It is housed in a 14-pin SOIC package with an operating temperature range from -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Integrates programmable current limit and slew rate control for controlled power-up sequences
• Provides under-voltage lockout and latched fault protection for system reliability
• Supports active-high enable functionality with power good reporting

Hot Swap Controllers Applications

• Hot-swappable backplane systems
• Industrial I/O modules requiring safe insertion
• Telecommunications equipment with live board replacement needs

Hot Swap Controllers Procurement Notes

Verify the specific suffix IDRG4 corresponds to the tape-and-reel packaging variant rather than the tube-packaged IPW version. Confirm that the ordering part number matches the required package type and reel quantity specifications defined in the official datasheet before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring controlled power ramping and robust fault management during board insertion. Ensure the input voltage range aligns with the system's bus voltage and verify that the thermal performance within the SOIC-14 package meets the application's power dissipation requirements under maximum load conditions.

Hot Swap Controllers Part Context

This part belongs to the TPS2331 series of hot-swap controllers, which are specialized power management ICs. It complements other Texas Instruments interface and logic components by providing critical power sequencing and protection functions essential for maintaining system integrity in high-availability environments.

Hot Swap Controllers Replacement Considerations

The TPS2331IPW is a pin-compatible alternative packaged in a tube instead of a reel. Verify that the functional specifications remain identical before substituting, as packaging differences may impact assembly line processes.
