TPS2413D

TPS2413D is Texas Instruments’ hot‑swap controller for protecting a live power rail during board insertion/removal. It drives an external N‑channel MOSFET on the high side to limit inrush, protect against shorts, and soften startup. The load current is sensed with an external resistor; the device trims the gate to keep current at a programmable limit. It provides undervoltage lockout, overcurrent/short‑circuit protection (with fault reporting and optional restart behavior), and overvoltage protection. A status/fault output signals events. It’s commonly used in hot‑swap/backplane applications such as servers, telecom, and other systems requiring safe power sequencing, and typically comes in an 8‑pin package. The “D” suffix denotes a specific variant/package grade within the TPS2413 family.

TPS2413D is TI’s high-side hot-swap controller with current limit. Equivalent devices from other vendors include:
- LTC4366 / LTC4367 (Analog Devices/Linear Technology) – hot-swap controllers with adjustable current limit and inrush control
- NCP4300 / NCP4317 (On Semiconductor) – hot-swap controllers with current limit and protection features
Note: exact specs (voltage range, current limit, enable/UVLO) vary; pick based on your rail and timing requirements.

TPS2413D features (high-level):
- Single-channel hot-swap controller that protects a load during insertion/removal
- Drives an external N-channel MOSFET for high-side switching
- Adjustable current limit via sense resistor; fast overcurrent protection
- Inrush control with soft-start/slp to limit turn-on current
- Undervoltage lockout (UVLO) with hysteresis
- Overvoltage/short-circuit protection
- Thermal shutdown protection
- Enable input for controlled turn-on/off
- Fault/status signaling (fault output) for MCU monitoring
- Small footprint in an 8-pin package; suited for space-constrained designs
- Intended for a broad input range common to power rails
Note: exact pin functions and electrical specs (e.g., current-limit range, voltage range) are defined in the datasheet.

TPS2413D is an 8‑pin device (D package) that functions as a hot‑swap/current‑limit controller. It drives an external N‑channel MOSFET to protect a power rail during module insertion and overload. Features include enable/shutdown control, current‑limit sensing (via a sense resistor), and a fault/status indication output. Typical pins handle VIN, GND, VCC/logic, GATE (to the MOSFET), IS/ISENSE, ILIM (for setting the limit), EN/SHDN, and FAULT/STATUS.

- Manufacturer: Texas Instruments (TI).
- What kind of company: an American multinational semiconductor design and manufacturing company that creates analog, mixed-signal, and embedded processing ICs.

TPS2413D is a high-side load switch with current limit and thermal protection. Key application areas:
- Hot-swap protection and power-on sequencing in backplanes, servers, telecom and industrial equipment
- Inrush-current limiting on DC rails
- Short-circuit/overcurrent protection for automotive and consumer electronics
- DC power distribution for USB/peripherals and embedded systems
- Protection for battery-powered devices requiring safe power-up and fault protection
Note: It’s used to gate and protect power rails while controlling inrush and faults.

TPS2413D is in an 8‑pin SOIC (Small-Outline) package; TI marks this as the D‑package variant.
