概述

Description

NCP5217AMNTXG is ON Semiconductor’s NCP5217 family device—a high-side, current-limited power switch intended to gate a supply rail to a downstream load. It provides enable control and protection features such as overcurrent/short-circuit protection, undervoltage lockout, and thermal shutdown, making it suitable for safe power switching in portable electronics.
Key points:
- Purpose: simple, safe power switch for main rails
- Protections: overcurrent, UVLO, thermal shutdown (and often reverse-current protection per variant)
- Packaging/variant: “XG” indicates RoHS/lead-free reel options; typically an 8-pin small package (e.g., MSOP-8/TSSOP-8) variant
- Applications: battery-powered devices, cameras, wearables, and other consumer electronics needing reliable rail switching
For exact electrical specs (input range, current limit, on-resistance, enable logic), consult the NCP5217 datasheet and product selector.

Features

NCP5217AMNTXG is a microcontroller supervisor/reset IC from ON Semiconductor. Key features (typical for the NCP5217 family):
- Power-on reset (POR) to guarantee MCU startup in a valid state
- Reset output (push-pull, active-low) to reliably drive MCU resets
- Manual reset input for external forcing of a reset
- Either fixed or selectable/adjustable reset threshold options
- Very low quiescent current
- Brown-out/voltage supervision with protection against undervoltage
- Wide operating supply range and temperature range suitable for common microcontroller/js applications
- Small, RoHS-compliant package (AMNTXG variant)
Note: exact thresholds, current values, and pinout depend on the specific variant and package. For precise specifications, consult the NCP5217AMNTXG datasheet.

Package

NCP5217AMNTXG uses an 8-pin SON-8 package (2×3 mm), RoHS-compliant.

Pinout

- Pin count: 8 pins (8-pin package).
- Function: High-side load switch with current limit and enable control; provides power to a load from VIN with protection (reverse-current/overcurrent) in an 8-pin package.

Manufacturer

- Manufacturer: ON Semiconductor (ON Semiconductor Corporation)
- What kind of company: A global American semiconductor company that designs and manufactures energy-efficient integrated circuits and components (power management, sensors, analog/digital ICs) for automotive, industrial, communications, and consumer markets.

Application

NCP5217AMNTXG is a voltage regulator/PMIC. Typical application areas:
- Portable and battery-powered devices (phones, wearables, cameras)
- Automotive electronics (sensors, control modules)
- Consumer electronics (TVs, audio equipment, set-top boxes)
- IoT and industrial sensors/gateways
- Embedded systems needing local, efficient DC regulation for MCUs, RF front-ends, and other rails
