ACNU-250L
ACNU-250L
1MBd Optocoupler in 11-mm SSO8
Package
Data Sheet
Description
The Broadcom® ACNU-250L is a single-channel 1MBd
optocoupler in an SSO8 footprint.
This 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.
The ACNU-250L is suitable for isolated communication
logic interface and control in high-voltage power systems,
space-constrained industrial applications, renewable
inverters and medical equipments. This package platform
features wide 11-mm creepage and 10.5-mm clearance,
high insulation voltage of Viorm = 1414 Vpeak and compact
footprint which is 40% smaller than the 400-mil DIP8
package.
Features
Wide supply voltage: 3.0V to 24V
11-mm creepage, 10.5-mm clearance in a compact
SSO8 package
TTL compatible
Open-collector output
40 kV/µs minimum common-mode rejection at
VCM = 1500V
Guaranteed performance within temperature range:
–40°C to +105°C
Worldwide safety approval:
– UL1577 recognized, 5000 Vrms/1 minute
– CSA Approval
– IEC 60747-5-5 Approval for Reinforced Insulation
Applications
Communications interface
Feedback elements in switching power supplies
Digital signal isolation for A/D, D/A conversion
MCU interface
Renewable energy inverters
