概要

Description

MAX17250ATD+T is a Maxim Integrated (now part of Analog Devices) power-management IC designed for battery-powered devices. It’s a highly integrated PMIC that provides DC-DC conversion and system supervision from a single Li‑ion battery, enabling multiple rails and protection features in one device. Typical capabilities include adjustable output rails, integration of high‑efficiency switching elements, protection (UVLO, over-current, short‑circuit), status/interrupt outputs, and a control interface (I2C/SPI in many variants). The ATD+T suffix indicates a specific packaging/tape‑and‑reel/temperature option for the device.
Common applications: smartphones, wearables, portable sensors, and other compact electronic systems needing efficient voltage conversion and battery management.
Note: For exact electrical specs (input range, output voltages, load current, efficiency, pinout, and package details), refer to the MAX17250ATD+T datasheet. If you share the specific application, I can summarize the relevant figures.

Features

Here are the common features of MAX17250ATD+T:
- Highly integrated synchronous buck regulator with internal MOSFETs
- Wide input range suitable for battery/automotive applications
- Adjustable output via external resistors (supports fixed options)
- High efficiency with advanced mode control (PWM and light-load burst/auto-skip)
- Programmable switching frequency
- Soft-start and output tracking
- Comprehensive protection: overcurrent/short-circuit, overvoltage, reverse current protection, thermal shutdown
- Enable input and Power-Good status output
- Low quiescent current in shutdown
- 28-pin package (ATD) with RoHS, Tape & Reel option
Note: exact voltage ranges, current capability, and pinout depend on the specific variant and data sheet revision.

Package

The MAX17250ATD+T uses a 16‑pin QFN package (3×3 mm) with an exposed pad. The “+T” suffix indicates Tape-and-Reel packaging.

Pinout

- Pin count: 16 pins (TDFN package, MAX17250ATD+T).
- Function: High-efficiency synchronous buck DC-DC regulator/power-management IC. Includes integrated MOSFETs for step-down voltage regulation, with adjustable output and typical PMIC features (enable, status/PGOOD, feedback, etc.).

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI). ADI is a global semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits. It acquired Maxim Integrated (the original maker of MAX parts), so MAX17250ATD+T is now part of ADI’s Maxim product portfolio.

Application

MAX17250ATD+T is a Li‑ion/Li‑poly battery fuel gauge (Impedance Track). Typical application areas:
- Single- and multi‑cell portable devices (phones, tablets, wearables, cameras, handheld tools)
- Automotive/industrial battery packs (12V–24V systems, power tools) needing accurate SOC and protection
- Energy storage/backup power systems (UPS, solar storage)
- IoT and medical devices requiring reliable state‑of‑charge reporting and battery protection.
