概要

Description

MAX14637CVB+T is Maxim’s evaluation board for the MAX14637 high-side hot-swap controller. It provides a ready-to-use platform to evaluate hot-plug protection, inrush control, and fault protection on DC power rails used in servers, storage, telecom backplanes, and other modular systems. The board includes the MAX14637 IC with its current-limit and soft-start circuitry, a sense resistor, protection components, and standard input/output connectors plus fault/status indicators. You can adjust the current limit, observe inrush, and monitor overcurrent, undervoltage/overvoltage protection, and fault-latch behavior via LEDs, test points, or control pins. The CVB designation indicates an evaluation board; the +T variant adds temperature-sensing/monitoring options to exercise over-temperature protection. It’s intended for bench testing to characterize response times, clamp behavior, and overall reliability before integrating the protection scheme into a final design.

Features

Key features of MAX14637CVB+T (concise):
- Eight high-side hot-swap switches for backplanes/complex power rails
- Input voltage range up to 60V with reverse polarity protection
- Programmable current limit per channel, with precise current-sense feedback
- Slew-rate controlled inrush (soft-start) per channel
- Protection: overcurrent/short-circuit (hiccup), overvoltage, undervoltage
- Thermal shutdown and thermal warning
- Fault/status reporting (per-channel and global) with open-drain outputs
- Enable/sequence control and programmable power-up sequencing
- Serial interface for configuration and monitoring (I2C/SPI-compatible)
- Automotive/industrial-grade operation (-40°C to +125°C)
- Compact CVB package with robust protection features
Note: Refer to the datasheet for exact electrical specs and pinout.

Package

The MAX14637CVB+T uses the CVB package: a 16‑pin QFN (4×4 mm) with an exposed pad; RoHS compliant and supplied on tape & reel (+T).

Pinout

- Pin count: 32 pins (CVB package, QFN-style).
- Function: Hot-swap/power-distribution controller. Drives an external MOSFET to protect a DC power rail, with programmable current limit, overcurrent/short-circuit protection, undervoltage lockout, soft-start, and fault/status signaling.

Manufacturer

- Manufacturer: Maxim Integrated (now part of Analog Devices, Inc.).
- What kind of company: A global semiconductor company that designs and manufactures analog, mixed-signal, and power-management integrated circuits.

Application

Applications: hot-swap protection and current limiting for multi-rail power architectures. Ideal for servers, backplanes, telecom/data-center equipment, storage systems, and industrial networks. Provides per-channel inrush control, overcurrent protection, fault latch, and rail sequencing for multi-rail DC supplies—enabling safe insertion/removal and protection of power supplies and distribution networks.
