MAX17300X+T

MAX17300X+T is Maxim Integrated’s family of highly integrated battery-management ICs for portable power. It combines a switch-mode charger/controller, power-path management, and safety features to charge Li‑ion/Li‑poly packs while supplying a system from multiple sources. The X+T suffix denotes a specific variant/packaging (T typically indicates tape-and-reel in datasheets).
Key features:
- Programmable charging: constant-current/constant-voltage charging with preconditioning and termination
- Integrated buck/boost regulator and system-power-path for efficient load sharing
- Digital control via I2C for charging current, voltage limits, and fault thresholds
- Comprehensive protections: overvoltage, overcurrent, short-circuit, thermal, reverse polarity; fault reporting
- Status indicators/alarms for the host MCU
Typical applications: smartphones, tablets, wearable devices, and other battery-powered equipment needing efficient charging and system power management.
For exact specs, pinout, and programming details, consult the MAX17300X+T datasheet and reference designs.

Here are the typical features you’ll find in the MAX17300X+T family (compact PMIC with multi-rail support). Verify the exact datasheet for your exact revision.
- Multi-rail power management: multiple high-efficiency buck regulators (synchronous)
- Integrated power-path and load-switching for seamless power delivery
- Li-Ion/Li-Pol battery charging path: programmable charge current and termination, safe charging
- I2C (and/or SPI) control and real-time monitoring of voltages, currents, and temperature
- Flexible sequencing and margining to power rails in a defined order on startup/shutdown
- Protection suite: UVLO/OVP/OCP/short-circuit protection, over-temperature protection
- Faults/status reporting with status flags and interrupt capabilities
- Optional features: wake/standby modes, watchdog timer, and programmable timing
- Packaging: Tape-and-reel option (X+T) with extended temperature variants
Note: exact rail count, maximum currents, input range, and available protections vary by device revision. Please consult the current MAX17300X+T datasheet for precise specifications.

- Pin count: 28-pin (QFN/LQFP variants common for MAX17300X+T).
- Function: A multi-rail DC-DC power-management IC (PMIC) controller for generating system rails (drives multiple synchronous buck regulators; external MOSFETs typically used). Suffix X+T denotes extended temperature capability and Tape & Reel packaging.

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

MAX17300X+T is Maxim’s high‑efficiency Li‑ion battery charger with integrated protection and power-path/system monitoring. Typical applications include:
- Portable electronics and wearables
- Cordless tools and other battery packs
- Backup/UPS power paths for embedded systems
- Solar/renewable energy storage and microgrids
- Industrial and telecom battery packs
- Automotive auxiliary power systems (12–24 V)
These devices benefit from safe charging, protection (over/short-circuit), and battery monitoring within a single IC.

MAX17300X+T uses a 28‑pin QFN package (6x6 mm) with an exposed pad; +T indicates Tape‑and‑Reel packaging.
