Product Description
Product Overview
The Broadcom ACPL-M49T is a single-channel, high-temperature, high CMR digital optocoupler designed for automotive applications. Operating at 20-kBd, it offers configurable low power and low leakage phototransistor functionality. Its SO-5 surface-mountable package and robust common-mode transient immunity (15kV/s minimum at VCM = 1500V) make it ideal for demanding environments. The ACPL-M49T provides reinforced insulation and reliability for critical automotive and high-temperature industrial applications, meeting AEC-Q100 test guidelines.
