概述

Description

MAX17332X22+T is a member of Maxim/Analog Devices’ MAX17332 family, a highly integrated power-management IC designed for battery-powered devices. The X22+T suffix indicates a 22‑pin QFN package in a tape‑and‑reel option. The device typically provides multi-rail, high-efficiency switching regulation (buck/boost) with integrated MOSFETs, along with protection and monitoring features and an interface for programming and status reporting (often I2C/SPI). It’s intended for portable applications such as smartphones, wearables, and other battery-powered systems, where efficient conversion from a Li‑ion battery to system rails is required, plus fault protection (overcurrent, overvoltage, thermal) and soft-start features. Exact capabilities (number of regulators, input/output voltage ranges, switching frequency, programming options) vary by variant, so consult the MAX17332X22+T datasheet and product page for precise specs and pinout.

Features

Here are the typical features you’d expect for MAX17332X22+T (Maxim PMIC family; exact specs should be confirmed from the datasheet for this package variant):
- Dual synchronous regulators with integrated MOSFETs
- Wide input range (generally 2.7V to 5.5V)
- Independent programmable outputs (via I2C) for multiple rails
- High efficiency and fast transient response
- I2C control interface with register map (soft-start, sequencing, fault reporting)
- Power-path management for seamless battery/system switching
- Protection: overcurrent, short-circuit, overvoltage, thermal/OT protection
- Status/diagnostic signals and interrupt outputs
- Enable/PGOOD control and fault alerts
- Small package: X22+T (Tape & Reel variant of the package)
Note: exact rail counts, voltage ranges, current capability, switching frequency, and package specifics can vary by variant. Please refer to the MAX17332X22+T datasheet for precise specifications.

Package

A 32‑lead QFN package, Tape‑and‑Reel (QFN-32, +T).

Pinout

- Pin count: 22 pins (X22 indicates a 22‑pin package, QFN/Tape-and-Release variant +T).
- Function: MAX17332X22+T is a Maxim power-management IC in a 22‑pin package; a high-efficiency switching DC-DC regulator controller (PMIC) used to generate system rails from a battery or input supply, featuring gate-drive outputs for external MOSFETs and typical PMIC protections/status signals.
