Overview
The TPS2330IDR, produced by Texas Instruments, is a single-channel hot-swap power controller designed to manage power in various hot-swap, plug, and dock applications. This device uses external N-channel MOSFETs as high-side switches and integrates several critical features such as overcurrent protection, inrush-current control, and power-good reporting. The TPS2330IDR ensures reliable operation by discriminating between load transients and faults, making it ideal for hot-swap power management in systems like hot-plug PCI and device bays.

Q & A
- What is the input voltage range for the TPS2330IDR? The input voltage range is from 3 V to 13 V.
- What type of MOSFETs are used with the TPS2330IDR? External N-channel MOSFETs are used as high-side switches.
- What is the purpose of the undervoltage lockout (UVLO) feature? The UVLO feature disables the external MOSFET if the voltage on VREG drops below 2.78 V and re-enables normal operation when it rises above 2.85 V.
- How does the power-good reporting work? The power-good reporting uses a transient filter and compares the VSENSE voltage to an internal reference to determine if the output voltage is within a specified tolerance.
- What is the standby supply current of the TPS2330IDR? The standby supply current is up to 5 μA.
- What are the package options for the TPS2330IDR? The device is available in 14-Pin SOIC and TSSOP packages.
- How does the circuit-breaker function work? The circuit-breaker has a programmable overcurrent threshold and transient timer, and it latches off the device if an overcurrent condition is sustained long enough.
- What is the role of the ENABLE pin? The ENABLE pin is active-low for TPS2330 and active-high for TPS2331, controlling the enablement of the external MOSFET.
- What is the discharge current of the DISCH pin? The discharge current of the DISCH pin is between 5 mA and 10 mA.
- What is the operating temperature range of the TPS2330IDR? The operating temperature range is from -40°C to 85°C.
