Broadcom's automotive isolation products with high precision r2 coupler provide enhanced insulation and reliability

     Broadcom's ACPL-C87AT and ACPL-C87BT automotive isolation amplifiers utilize superior optical coupling technology, Sigma-Delta analog-to-digital converters, chopper-stabilized amplifiers, and a fully differential circuit topology. To provide unmatched isolation mode noise suppression, low offset, high gain accuracy, and stability.

     ACPL-C87AT(±1% gain tolerance) and ACPL-C87BT(±0.5% gain tolerance) are designed for high precision DC voltage sensing in electronic motor drivers, DC/DC and AC/DC converters, and battery monitoring systems. ACPL-C87AT and ACPL-C87BT feature high input impedance and work analog input voltages up to 2.46V across the full span. The shutdown function provides power savings that can be controlled from an external power source, such as a microprocessor.

     High common-mode transient immunity (15 kV /μs) ACPL-C87AT and ACPL-C87BT maintain the accuracy and stability required to accurately monitor DC rail in high-noise voltage motor control environments. The electro-safety isolator is packaged in a compact, surface-mounted stretched SO-8 (SSO-8) package that complies with global regulatory safety standards.

     Broadcom R2Coupler Isolation products provide the enhanced insulation and reliability required for critical automotive and high-temperature industrial applications.
