TPS24713DGS - 18V Hot-Swap Controller w/ Power Limit | TI
MPN： TPS24713DGS ✓ 啟用中TPS24713DGS 概覽
A hot-swap controller is a power-management IC that safely inserts or removes a circuit card from a live backplane by controlling the gate of an external MOSFET as a soft-start element. The TPS24713 belongs to the hot-swap controller IC family within the broader category of power-management semiconductors, sitting between DC-DC converters and discrete protection circuits such as eFuses and PTC resettable fuses. By regulating inrush current and isolating faulty loads, hot-swap controllers prevent backplane collapse and connector arcing in multi-board systems.
Key features include 2.5 V to 18 V operating range, adjustable current limit, programmable FET SOA protection via the power-limiting loop, accurate 25 mV current-sense threshold that minimises sense-resistor losses, a power-good output for downstream sequencing, and an auto-retry fault response that latches off in fault conditions and automatically retries after a programmed interval. The combination of current-limit loop and power-limit loop provides superior SOA protection over current-limit-only competitors.
The TPS24713 uses a dual-loop architecture: an inner current-sense loop (trans-conductor amplifier at 25 mV) regulates inrush and steady-state current, while an outer power-limit loop (analog multiplier of VDS and ID) protects the external MOSFET against thermal runaway. The 25 mV sense threshold allows a 2 mΩ sense resistor for a 12.5 A load with minimal conduction loss, and the programmable power-limit timer balances SOA utilisation against nuisance tripping.
Typical applications include RAID and hot-plug disk drives, blade servers, redundant telecom -48 V distribution, PCI/PCIe hot-plug cards, and industrial high-side switches. The 10-pin VSSOP (DGS) footprint suits compact add-in cards and ATCA/IPMB designs. The auto-retry response is well suited to remote, unattended systems that must recover from transient faults without operator intervention.
When designing with this device, choose the external MOSFET's RDS(on) and SOA rating together with the sense resistor value to balance conduction loss against trip accuracy. The power-good output can directly drive an enable pin on a downstream DC-DC converter for sequenced power-up.

典型應用
TPS24713DGS 適用於 6 應用s: RAID Hot-Plug Disk Drive Backplane, Blade Server High-Side Switch, Telecom -48 V Distribution Card, PCI / PCIe Hot-Plug Add-In Card, Industrial High-Side Load Switch, Battery Management Inrush Limiter.
RAID Hot-Plug Disk Drive Backplane
The TPS24713DGS fits RAID and hot-plug disk drive backplanes because its 2.5 V to 18 V operating range covers both 5 V and 12 V drive rails. The 25 mV current-sense threshold supports accurate inrush limiting across multiple drive bays without dissipating excessive sense-resistor power. Auto-retry fault response recovers from transient hot-plug events without operator intervention. Designers typically pair the controller with a 30 V N-channel MOSFET and a 2 mΩ sense resistor for a 12.5 A load, plus a 10 uF gate bypass capacitor to control inrush dV/dt. The PGOOD pin can sequence downstream DC-DC converters in each drive bay.

Blade Server High-Side Switch
Blade servers use the TPS24713DGS as a per-card high-side protection switch on 12 V distribution rails. The device's power-limiting loop protects the external MOSFET against transient SOA stress during hot-insertion, while auto-retry handles momentary downstream faults. Compared to a simple eFuse, the TPS24713 offers higher accuracy (25 mV sense threshold) and programmable behaviour. The 10-VSSOP footprint suits the dense ATCA/AdvancedTCA form factor. Designers should size the sense resistor for IMAX at 1.2x nominal and program the power-limit timer to allow safe hot-swap transients.
推薦
Telecom -48 V Distribution Card
In telecom -48 V distribution cards, the TPS24713DGS sits on the high side of -48 V (with respect to return) for hot-swap insertion into backplanes. The 18 V upper limit is sufficient when the -48 V rail is locally regulated, and the 25 mV sense threshold minimises conduction loss in high-current paths. Auto-retry fault response is ideal for unattended remote sites where transient faults must clear without truck rolls. Designers commonly combine the controller with a 60 V BVDSS MOSFET and TVS clamp for transient protection.
推薦
PCI / PCIe Hot-Plug Add-In Card
The TPS24713DGS protects PCI and PCIe hot-plug add-in cards during insertion into a live backplane. The controller's power-limit loop prevents connector arcing and downstream rail collapse by ramping the MOSFET gate with a controlled inrush profile. The PGOOD output signals the host that the rail is stable, allowing the downstream core logic to come out of reset. Compared to discrete hot-swap designs using comparators, the TPS24713DGS integrates both current-sense amplifier and power-limiting multiplier in one IC. The 10-VSSOP footprint fits standard PCIe edge-connector area.
推薦
Industrial High-Side Load Switch
In industrial PLC and field I/O systems, the TPS24713DGS serves as a high-side load switch with hot-swap and over-current protection. The 2.5 V to 18 V operating range covers 5 V, 12 V, and 24 V industrial buses (with appropriate front-end regulation for 24 V). The 25 mV sense threshold allows accurate current limiting even at low voltages. Auto-retry fault response handles inductive kickback and short-duration overloads without latching. The -40 C to +85 C operating temperature range meets industrial environmental specifications. Designers should add a TVS across the MOSFET drain for surge immunity.
推薦
Battery Management Inrush Limiter
The TPS24713DGS can act as an inrush-current limiter for battery management systems where a large bulk capacitor is charged from a battery or charger. The power-limit loop protects both the controller and the external MOSFET during the initial charging transient, while auto-retry recovers from any downstream short. The 2.5 V lower operating limit suits single-cell Li-ion applications. Compared to a simple PTC or NTC thermistor, the TPS24713DGS offers programmable and repeatable behaviour. Designers should tune the gate capacitor value to set the inrush dV/dt profile.

設計說明
The TPS24713DGS dissipates quiescent current (typically 1 mA at 12 V) into the 10-VSSOP package which has limited thermal headroom. At 18 V input the controller dissipation is approximately 18 mW, well within the package's 200 C/W junction-to-ambient rating. Estimated: for high-input-voltage designs above 15 V, designers should provide a small copper area (>= 0.1 sq inch) on Pin 2 (IN) for thermal relief; without it the junction temperature rise is negligible at full supply.
Place the external sense resistor (RSENSE) as close to the SENSE pin (Pin 4) as possible to minimise parasitic inductance. Use a 4-wire (Kelvin) connection for accurate current measurement. The gate capacitor (CGATE, typically 10 nF to 100 nF) controls the inrush dV/dt and should be placed adjacent to the GATE pin (Pin 7). Keep the TIMER capacitor (Pin 6) close to the IC and use a low-leakage ceramic or film type for accurate fault timing.
Do not exceed the 20 V absolute maximum on IN or OUT pins; transients above this can latch up the controller. The PGOOD pin (Pin 8) is open-drain and requires an external pull-up resistor to logic supply. The FLT pin (Pin 9) is also open-drain. Do not float the EN pin (Pin 10); tie it high for always-on operation or drive with a logic signal for sequenced power-up. Avoid using the TPS24713DGS for voltages below 2.5 V - the undervoltage lockout will not release.
Keep the high-current path (drain of MOSFET -> load) physically separated from the low-current sense path to avoid noise coupling. The PGND pin (Pin 1) should connect directly to the system ground plane at the sense resistor's ground return. Estimated: an EMI-optimised layout places the input bulk capacitor within 5 mm of the MOSFET source pin and the controller within 10 mm of the gate, minimising parasitic inductance and switching transients.
