Maxim Integrated’s High-Voltage Battery Sensor Extends Battery Life and Supports Highest Automotive Safety Rating
Maxim's 70V-tolerant, 12-cell sensor meets toughest OEM standards for automotive safety, performance, and reliability.
San Jose, CA—September 20, 2012—Maxim Integrated Products, Inc. (NASDAQ: MXIM) introduces the MAX17823, a fourth-generation high-voltage battery sensor for mission-critical automotive and industrial lithium-ion battery and fuel cell applications. Offering a full suite of proprietary integrated ISO-26262 diagnostic features, the MAX17823 maximizes electric and hybrid electric vehicle driving range while ensuring battery and fuel cell safety and reliability.
A proprietary, differential UART communications link is automotive EMC-hardened, enabling uninterrupted cell monitoring during battery pack service disconnect and eliminating costly digital isolators. An innovative shutdown feature safely enters all daisy-chain devices into submicro-ampere sleep mode when a host microcontroller loses 12V power. ASIL-D (Automotive Safety Integrity Level "D", per ISO-26262) compliance is achieved and maintained with unmatched, accurate 96-cell, 100 measurements-per-second performance. The 96-cell hot-plug immunity ensures highest reliability during BMS (battery management system) manufacturing.
