概述

Description

MAX17300X+T is Maxim’s family of battery-management ICs (PMICs) for Li‑ion/Li‑poly packs. They are highly integrated devices that combine charging, system power-path management, protection, and monitoring (often including fuel gauging) in a single chip. Features typically include programmable charging (current/voltage), battery status monitoring, protections (over/under-voltage, overcurrent, short-circuit, thermal), and a digital interface (I2C/SPI) for host control and status. Many variants also include an internal DC-DC regulator to power the system from the battery. The X+T suffix denotes a specific variant in the MAX17300 family, with “T” usually indicating Tape‑and‑Reel packaging. Applications: portable devices such as smartphones, tablets, wearables, and other battery-powered products where compact BOM and efficient power management are desired.

Features

Here are the typical features of the MAX17300X+T family (concise):
- Single-cell Li‑ion/Li‑polymer charge management with an integrated power path and fuel gauge
- Input on USB/DC source (wide input range, optimized for 5V USB)
- CC/CV charging with programmable charge current and 4.2V termination
- Preconditioning for deeply discharged cells
- Coulomb counter and state-of-charge estimation (fuel gauge)
- I2C control/monitoring interface for status and programming
- Dynamic power-path/load sharing: supports system load while charging
- Safety protections: overcurrent, overvoltage, short-circuit, over/under-temperature, reverse polarity
- Temperature sensing/monitoring via external NTC
- Low quiescent current and high efficiency
- Small-packaged device with X+T suffix indicating extended temperature range and tape-and-reel packaging
Note: Exact current/voltage ranges and package options vary by specific device variant within the MAX17300X+T family—check the datasheet for your exact part number.

Package

MAX17300X+T uses a 16‑pin TQFN package (3.0 × 3.0 mm) with Tape‑and‑Reel packaging.

Pinout

- Pin count: 24 pins (in the common QFN/TQFN package for MAX17300X+T).
- Function: Battery-management IC for Li-ion/Li-poly packs — integrates charging control, protection (overcurrent/overvoltage/short-circuit), and coulomb-gauge functionality for pack monitoring.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI). It is an American multinational semiconductor company that designs, manufactures, and markets analog, mixed-signal, and digital signal processing integrated circuits (ADI acquired Maxim Integrated, the original maker of MAX parts).

Application

MAX17300X+T is a battery-management/PMIC family. Common applications include:
- Portable consumer electronics (smartphones, tablets, wearables)
- Medical devices with onboard Li‑ion protection and gauging
- Industrial portable equipment and handheld tools
- Automotive battery-powered subsystems and telematics
- Energy-storage systems (UPS, solar/battery backup)
- Remote sensing and telecom equipment requiring battery support
These parts provide gauging, protection, and power-management for embedded, battery-powered systems.
