Description

MAX14931AAWE+ is a hot‑swap controller from Maxim Integrated designed to protect and manage a power rail during card insertion/removal and power sequencing. It drives an external MOSFET to control inrush current and overall rail health, while monitoring voltage and current to detect faults.
Key ideas:
- Allows controlled turn‑on/turn‑off with programmable soft‑start and current limit
- Provides fault protections (e.g., over/undervoltage, overcurrent/short‑circuit, thermal monitoring)
- Outputs a fault/status signal for system signaling and safe shutdown/retry behavior
- Suited for high‑reliability systems like backplanes, servers, telecom equipment, and data‑center power rails
Usage note:
- Typically paired with an external MOSFET in series with the supply
- Used to ensure safe startup, robust overcurrent protection, and orderly rail disconnection if problems occur
For exact voltage range, current‑limit settings, timing, and pinout, consult the MAX14931AAWE+ datasheet and packaging details.

Package

28‑pin TQFN (5x5 mm), Pb‑free RoHS (WE+ variant).

Pinout

- Pin count: 20 pins (20-pin package)
- Function: High-side hot-swap controller with an external N-channel MOSFET gate driver, providing inrush/current-limit protection and fault protection (UVLO, overcurrent, etc.) for a supply rail.

Manufacturer

- Manufacturer: Maxim Integrated
- What kind of company: An American semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (now part of Analog Devices).

Application

Applications (typical):
- Hot-swap protection and current limiting for DC power rails
- Power-supply sequencing and fault protection in servers, telecom, and data-center equipment
- Backplanes and distribution boards, ORing/ideal-diode architectures
- High-side switch control for redundant supply architectures
- Industrial and battery-backed systems, and point-of-load control for DC-DC converters
MAX14931AAWE+ is used in power-management and protection roles across these areas.

Equivalent

MAX14931AAWE+ is an automotive single‑channel high‑side switch with current limit and fault protection (hot‑swap). Equivalent parts from other vendors include:
- TI: TPS1Hxxx/TPS269x high‑side switches and hot‑swap controllers
- Onsemi: NCP3xxx/NCP18xx hot‑swap controllers
- Analog Devices: ADM1166/ADM1262 hot‑swap controllers
- STMicroelectronics: VIPower high‑side switches (VIP/M0/M1 families)
- Infineon: VIPower/NovalithIC families
Exact cross‑reference depends on voltage/current ratings, packaging, and automotive grade requirements.
