MAXREFDES1299

Description

The MAXREFDES1299 is a ready-to-use hardware platform for monitoring, balancing, and protecting the 4-cell battery packs in battery-powered applications such as power tools, smart devices, battery backups. Mobile devices require high-capacity rechargeable batteries to provide system power. These systems typically use lithium-ion (Li+) batteries due to their lightweight and high energy density. Every Li+ battery needs a protector to prevent damage and hazardous outcomes when subjected to abnormal voltages, current, and temperatures. Mobile devices need an accurate battery status indicator to prevent a premature or abrupt shutdown. Our fuel gauges monitor the remaining battery charge using a proprietary ModelGauge™ m5 algorithm to provide high accuracy state of charge (SOC). This reference design uses MAX17320 which monitors the voltage, current, temperature, determines battery SOC, and protects the battery from failures.

Features & Benefits

• Monitors cell voltages, pack current, pack temperatures, balances cells, and protects by controlling charge or discharge field-effect transistors (FETs).
• Hardware protection for overcurrent in charge/discharge, short circuit in discharge, overvoltage, undervoltage, over temperature and under temperature.
• External cell balancing up to 600 mA per cell.
• I2C Interface with clock frequency of 400kHz.
