ACPL-C87BT

ACPL-C87AT/ACPL-C87BT Automotive High Precision DC Voltage Isolation Sensor Data Sheet Description The Broadcom® ACPL-C87AT/C87BT isolation sensors utilize superior optical coupling technology, with sigma-delta (-) analog-to-digital converter, chopper stabilized amplifiers, and a fully differential circuit topology to provide unequaled isolation-mode noise rejection, 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 drives, DC/DC and AC/DC converter and battery monitoring system. The ACPL-C87AT/C87BT features high input impedance and operate with full span of analog input voltage up to 2.46V. The shutdown feature provides power saving and can be controlled from external source, such as microprocessor. The high common-mode transient immunity (15 kV/μs) of the ACPL-C87AT/C87BT maintains the precision and stability needed to accurately monitor DC rail voltage in high noise motor control environments. This galvanic safe isolation solution is delivered in a compact, surface mount stretched SO-8 (SSO-8) package that meets worldwide regulatory safety standards. Broadcom R2Coupler® isolation products provide the reinforced insulation and reliability needed for critical automotive and high temperature industrial applications.
