Broadcom ACNT-H50L 1MBd Optocoupler

Broadcom ACNT-H50L 1MBd Optocoupler uses an insulating layer between the light-emitting diode and an integrated photon detector to provide electrical insulation between input and output. Separate connections for the photodiode bias and output transistor collector increase the speed up to a hundred times over that of a conventional photo-transistor coupler by reducing the base-collector capacitance.

Features

1Mb/s high speed
TTL compatible
15mm stretched SO8 package package
Open-collector output
15kV/μs minimum common-mode rejection at V_CM = 1500V
Guaranteed performance within a temperature range of –40°C to +105°C

Worldwide safety approval
- UL1577 recognized: 7500V_rms for 1 minute
- CSA approval
- IEC 60747-5-5 approval for reinforced insulation

Applications

High voltage power systems, e.g., 690V_AC drives
Renewable energy inverters
Feedback elements in switching power supplies

Digital isolation for A/D, D/A conversion digital field
Communications interface
MCU interface
