Intersil ISL94202EVKIT1Z

电源管理电池监控器板

Overview

Intersil, a subsidiary of Renesas Electronics announces the ISL94202 3-to-8 cell battery pack monitor that supports Li-ion and other battery chemistries used in applications such as vacuum cleaners, lawn equipment, handheld power tools, e-bikes, scooters, toys, and energy storage systems. Li-ion batteries are smaller, weigh less, and deliver longer battery life than other battery chemistries, but require monitoring and protection for safe use. The highly integrated ISL94202 battery pack monitor enables ultra-small 2-terminal designs, and accurately monitors, protects and cell balances rechargeable battery packs to ensure safe operation and charging. The ISL94202 operates as a stand-alone battery protection system using an internal state machine with five pre-programmed modes for accurately balancing and controlling each battery cell. It monitors and protects the battery pack from catastrophic events such as hardware faults, short circuit conditions, and cell voltage overcharge/over-discharge and meets the UL2054, UL2271/72 and IEC62133 specified pack safety requirements. Designers can program the ISL94202 battery monitor�s protection settings to enable the battery packs without requiring an external microcontroller. If required, the ISL94202 can also communicate with an external microcontroller via I2C serial bus to provide additional fuel gauge measurements, including state of charge and state of health information. Precise fuel gauge status is provided by the device�s high-side current measurement feature.
