Vue d'ensemble

Description

The LTC2907CTS8#TRPBF is a Linear Technology (now Analog Devices) hot‑swap controller in an 8‑pin package (CTS8), shipped in Tape & Reel, lead‑free. It drives an external N‑channel MOSFET to protect and control a power rail when a board is inserted into a live supply.
Key points:
- Purpose: limit inrush current and provide overcurrent protection on hot‑swap events.
- How it works: monitors load current via an external sense resistor and clamps the MOSFET gate to achieve soft‑start and current limiting.
- Protections and signals: includes input protection (UVLO/O/V protection), and a fault/status indication output to inform a system controller.
- External parts: requires an external MOSFET and sense resistor; the current limit is set by these components.
- Applications: server and telecom power rails, hot‑swap capable power supplies, disk drives, and other systems needing safe insertion/removal of boards.
CTS8 indicates the 8‑pin package; TRPBF denotes Tape & Reel, RoHS/lead‑free packaging.

Features

LTC2907CTS8#TRPBF features (typical)
- I2C-controlled voltage supervisor with watchdog
- Programmable watchdog timeout and reset behavior
- Power-on reset with automatic assertion on supply ramp
- Window/monitoring capability with status/flag outputs
- Manual reset input and programmable reset polarity
- Status/interrupt outputs to host MCU
- Low quiescent current; suitable for portable apps
- Wide supply range (compatible with common rails)
- 8-pin MSOP package (CTS8) and RoHS-compliant tape-and-reel (TRPBF)
- Extended temperature range for industrial use
Note: Exact electrical specs (thresholds, delays, current consumption, etc.) are in the datasheet.

Package

The LTC2907CTS8#TRPBF uses an 8-lead MSOP package (MSOP-8). It is Pb-free and delivered in Tape & Reel (TRPBF).

Pinout

- Pin count: 8 pins (8-pin package)
- Function: Power-fail/power-supply monitor for supervision; detects input voltage status and provides a fault/flag output to indicate undervoltage or power loss (often used to generate a reset or warning signal for a microcontroller).

Manufacturer

Manufacturer: Analog Devices, Inc. (the Linear Technology brand prefix “LTC” comes from Linear Technology, which ADI acquired in 2017).
What kind of company: A multinational semiconductor company that designs and manufactures analog, mixed-signal, and related integrated circuits.

Application

Designed for hot‑swap protection and current limiting of DC rails in high‑reliability systems. Typical applications include hot‑plug PCIe/PCI cards, servers, telecom and network equipment, storage backplanes, and multi‑rail power supplies. It provides inrush control for large output capacitors, overcurrent/short‑circuit protection, undervoltage lockout, and safe rail sequencing during card insertion/removal.

Equivalent

LTC2907CTS8#TRPBF is a hot‑swap controller with current limit and fault reporting. Functionally similar parts from other vendors include:
- TI: TPS2440 family (TPS2440/TPS2442/TPS2443)
- ON Semiconductor: NCP4680/NCP4681 (hot‑swap controllers)
Always verify pinout and electrical specs (current limit, delay, fault signaling) and use a cross‑reference from the distributor for an exact substitute.
