Overview
Description
MAX17224ENT+T is a Maxim Integrated battery-management IC designed for Li‑ion/Li‑polymer packs. It combines fuel‑gauge capabilities (SOC estimation via coulomb counting and voltage/current monitoring) with power‑management features and protection for portable devices. The device typically provides an I2C/SMBus interface to report status (state of charge, voltage, current, temperature) to a host controller, plus programmable alerts and safety protections (over/under voltage, overcurrent/short, and temperature limits). The ENT+T suffix indicates a lead-free (RoHS) part in an extended/industrial temperature range and Tape‑and‑Reel packaging, suitable for production environments. Common applications include smartphones, tablets, wearables, and other battery-powered equipment requiring accurate battery status, protection, and efficient power management. For exact features and pinout, refer to the specific MAX17224 data sheet and land pattern.
Features
Here are the typical features of the MAX17224ENT+T (family features, with ENT = extended temp and +T = Tape & Reel):
- Multi-output synchronous DC-DC regulator with integrated MOSFETs
- Independent, programmable output rails (voltage per channel)
- Wide input range suitable for battery/USB-powered systems
- High efficiency across load conditions
- PWM/PFM operation for light-load efficiency
- Digital control via I2C/SPI interface for sequencing, voltages, and fault handling
