ACPL-C799T-000E

Overview

The ACPL-C799T-000E is an automotive-grade isolated modulator manufactured by Broadcom Limited. It utilizes sigma-delta modulation technology to provide high-precision signal isolation in industrial environments. The device operates on a dual power supply ranging from 4.5 V to 5.5 V and features an 8-pin SSOP package. Designed for applications requiring accurate measurement of phase currents and bus voltages, it offers high common-mode rejection and built-in safety insulation. This component serves as a replacement for Hall effect sensors in power converters.

Procurement Notes

Verify the specific suffix 'T' indicates the tape-and-reel packaging format when sourcing. Confirm automotive grade compliance requirements against project specifications. Ensure the 8-pin SSOP stretched package dimensions fit the target PCB layout. Check for RoHS compliance status prior to final procurement decisions.

Selection Notes

Select this component when high precision and automotive reliability are required for isolated signal transmission. Compare performance metrics against Hall effect sensors if cost or size constraints exist. Verify that the dual supply voltage range matches the system's available power rails. Consider the sigma-delta modulation bandwidth limitations for high-frequency applications.
