Descripción general

Description

ADM1276-3ACPZ-RL is Analog Devices’ triple hot‑swap controller. It protects and soft‑starts three high‑voltage rails when boards are plugged in or power cycled. Each channel provides overcurrent/short‑circuit protection, undervoltage/overvoltage protection, and fault signaling. It typically drives external N‑channel MOSFETs and works with sense resistors to set current limits. The device enables controlled power sequencing and fault indication across three rails, making it suitable for hot‑swap protection in servers, telecom equipment, and industrial electronics. Package: ACPZ (LFCSP) in tape‑and‑reel (RL).

Features

ADM1276-3ACPZ-RL is a hot‑swap controller with fault protection for safe insertion/removal on live boards. Key features include:
- 3 A peak current limit (set by external sense resistor)
- External N‑channel MOSFET gate drive for hot‑swap switching
- Programmable inrush control with soft‑start to limit startup surge
- Overcurrent/short‑circuit protection with latch
- Overvoltage and undervoltage lockout
- Thermal protection with latch
- Fault/status reporting (fault/OK signals for microcontroller monitoring)
- Adjustable timing/ramp settings via external components
- Suitable for a wide system rail range and packaged in ACPZ with Tape & Reel (-RL)
Note: For exact electrical specs (voltage ranges, timing values, pinout) please consult the current ADM1276 datasheet.

Package

ADM1276-3ACPZ-RL is in a 16‑lead plastic TSSOP package (PZ code), RoHS compliant; RL indicates tape-and-reel packaging.

Pinout

- Pin count: 8 pins (8‑lead package).
- Function: High‑side hot‑swap controller with current limiting; provides soft‑start, overcurrent/UL/OV protection, and drives an external MOSFET to protect a power rail from inrush and fault conditions (3 A version in ADM1276 family).

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI).
Company type: A US-based multinational semiconductor company that designs and manufactures analog, mixed‑signal, and DSP integrated circuits.

Application

Application areas:
- Hot‑swap protection for backplanes and server blade systems (boards inserted into backplanes)
- Power-supply/DC‑DC modules in servers, storage, telecom, and industrial equipment
- Networking gear and other high‑availability systems requiring current‑limit and fault‑detection protection
