TPS24713DGSR Visão geral
A hot-swap controller is a specialized power-management IC that allows a circuit board to be inserted into or removed from a live backplane without causing damaging inrush currents, voltage droops, or connector arcing. Hot-swap controllers sit in the hierarchy: hot-swap controller -> power management IC -> semiconductor, and are essential building blocks for high-availability systems that require hot-plug capability.
Key features include a 2.5 V to 18 V operating supply range, programmable power-limiting fault current, programmable fault timeout, an open-drain power-good (PG) output, and an open-drain fault (FLT) indicator. The auto-retry variant (TPS24713) retries after a fault, while the latched variant (TPS24712) latches off. The device is part of the TPS24710/11/12/13 family, with the TPS24710/11 differing in fault response timing.
The TPS24713 uses an external N-channel MOSFET sense element with a current-sense resistor (RSENSE) and a high-side gate driver. The sense voltage across RSENSE is amplified and compared against a programmable power-limit reference, allowing the controller to regulate power dissipation rather than peak current - a key differentiator from current-only hot-swap controllers. This architecture provides predictable SOA operation for the MOSFET under varying load conditions.
Typical applications include server and storage hot-plug bays, RAID controllers, 12 V distributed-power systems, telecom plug-in modules, industrial PC cards, and ATCA/AdvancedTCA cards. Its wide 2.5 V to 18 V input range covers 3.3 V, 5 V, and 12 V rails, making it broadly applicable across enterprise, telecom, and industrial platforms.
When designing with the TPS24713, pay attention to the sense-resistor selection and the associated power dissipation: choose a low-ohm RSENSE (typically 5-50 mOhm) to minimize loss, but ensure the resulting power-limit threshold is above maximum steady-state load. Add a gate-source pull-down resistor (typically 100 kOhm) for safe MOSFET turn-off during controller power-down.

Aplicações típicas
TPS24713DGSR é adequado para 6 aplicaçãos: Server Hot-Swap Bays, 12 V Distributed Power Hot-Plug, RAID Controller Card Insertion, Industrial PC Card Slot Protection, Telecom Plug-In Module Power, Battery Hot-Swap / Power Path.
Server Hot-Swap Bays
The TPS24713DGSR is purpose-built for server and storage hot-swap bays operating on 12 V ATX rails. Its 2.5 V to 18 V supply range, programmable power-limiting at the RSENSE input, and open-drain PG output integrate directly with baseboard management controllers (BMCs) for IPMI-compliant fault reporting. The auto-retry behavior is well-matched to redundant PSU topologies where transient faults must clear without operator intervention. Compared with current-only hot-swap ICs, the TPS24713's power-limit loop protects the MOSFET SOA under high-VIN short-circuit conditions, enabling smaller MOSFET selection at the same fault-current threshold.
Recomendado
12 V Distributed Power Hot-Plug
In 12 V distributed-power systems such as ATCA/AdvancedTCA cards and telecom plug-in modules, the TPS24713DGSR provides safe live-insertion without arcing connectors or tripping upstream breakers. Its wide 2.5-18 V supply covers both 5 V and 12 V rails from a single IC SKU, reducing BOM complexity. The power-limiting feature, configured via the PLIM pin and external RSENSE, caps inrush energy during insertion and protects downstream bulk capacitors from voltage collapse.
Recomendado
RAID Controller Card Insertion
RAID and storage controller cards require hot-plug capability to allow online capacity expansion without server downtime. The TPS24713DGSR's 18 V maximum input supports 12 V backplane rails directly, and its power-limiting architecture prevents the inrush surge that would otherwise disturb adjacent cards sharing the same power rail. The open-drain FLT output can drive a system LED or BMC interrupt to alert operators of repeated faults, while auto-retry handles transient shorts from cable misalignment.
Recomendado
Industrial PC Card Slot Protection
Industrial PCs and compactPCI systems use the TPS24713DGSR to protect PCI/PCIe card slots from short-circuit damage during live insertion. The -40C to +85C operating range suits factory-floor and outdoor cabinet deployments. The programmable TIMER pin sets the fault timeout duration, allowing designers to tune the IC for varying load-capacitance profiles. Combined with the open-drain PG signal, this enables deterministic hot-plug sequencing required by industrial automation standards.
Recomendado
Telecom Plug-In Module Power
Telecom plug-in modules and line cards on -48 V (isolated to 12 V/5 V) backplanes use the TPS24713DGSR for safe insertion into live shelves. Its compact VSSOP-10 (DGS) footprint and minimal external component count simplify the dense PCB layouts typical of telecom equipment. The auto-retry fault response handles transient shorts caused by bent pins or connector contamination without requiring a service truck roll.
Recomendado
Battery Hot-Swap / Power Path
In portable or battery-backed equipment where hot-swap of battery packs or DC sources is required, the TPS24713DGSR can be configured with the appropriate MOSFET to limit inrush from a charged source. The PLIM and TIMER pins provide full programmability for different battery chemistries and load profiles. While the part was originally designed for backplane applications, its 18 V max supply covers most single-cell and multi-cell lithium battery stacks after regulation.

Notas de projeto
Choose RSENSE to set the power-limit threshold: PLIM (in V) / RSENSE (in ohms) approximates the regulated load power divided by VIN. For a 12 V rail with PLIM=1 V and RSENSE=10 mOhm, the power limit is roughly 120 W (10 A at 12 V), which sets the inrush and steady-state current envelope. Use a 1% tolerance sense resistor to maintain accuracy across temperature. Estimated: assumes PLIM programmed to 1 V and load power = VIN x ILIM.
RSENSE dissipation is I^2 x RSENSE. For a 10 A steady-state load with RSENSE=10 mOhm, the sense resistor dissipates 1 W continuously. Select an 0805 or larger resistor rated for at least 2x the calculated power to keep temperature rise within 50 C. Place RSENSE close to the TPS24713DGSR's VSENSE pin to minimize parasitic resistance and inductance that would otherwise disturb the current-sense signal.
Use a Kelvin connection to RSENSE for accurate current sensing: route the high-side and low-side VSENSE traces directly to the resistor pads, never through the high-current path. Place the TIMER capacitor as close as possible to pin 3, with a short ground return, to prevent fault-timeout variation. Keep the high-current traces (VIN -> MOSFET -> OUT) short and wide to reduce parasitic inductance and voltage spikes at turn-on.
Do not omit the gate-source pull-down resistor on the external MOSFET (typically 100 kOhm from GATE to source). Without it, the MOSFET may partially turn on during controller power-up and create a momentary short. Also, ensure the VIN supply decoupling capacitor (1 uF minimum) is placed within 5 mm of pin 8 - inadequate decoupling causes the controller to brownout and reset during hot-plug events.
