Competitively Priced Miniature Detectors Extends Working Insulation
Voltage to 1140V in a Wide Range of Industrial Control Applications
SAN JOSE, Calif. & SINGAPORE--(BUSINESS WIRE)--Nov. 23, 2009--
Avago Technologies (Nasdaq:AVGO), a leading supplier of analog interface
components for communications, industrial and consumer applications,
today announced two new miniature voltage/current threshold detection
optocouplers for use in a wide range of industrial control applications.
The ACPL-K370/K376 optocouplers are designed to detect AC/DC sources and
convert the voltage to a logic interface across an optical coupling
barrier to provide safe isolation in electronically noisy environments
found in industrial applications. These voltage/current sensing
optocouplers are ideal for use in applications such as limit switch
sensors, low voltage detectors, relay contact monitors, relay coil
voltage monitors, and current sensors.
The new ACPL-K370/K376 series, which are an upgrade from Avago’s
HCPL-0370/3700/3760 optocoupler family, utilizes threshold sensing input
buffer ICs which permit control of threshold levels over a wide range of
input voltages up to 1140 Vpeak, with a single external resistor. Some
of the key benefits provided by this new optocoupler series include a
smaller stretched SO-8 (SSO-8) package which meets 8mm clearance and
creepage requirements, and requires 30 percent less printed circuit
board space compared to dual-inline packages (DIP-8). Additionally, the
input buffer of these optocouplers offer several key features to enhance
threshold sensing such as hysteresis for extra noise and switching
immunity, a diode bridge for easy use with AC input signals, and
internal clamping diodes to protect the buffer and light emitting diode
(LED) from a wide range of over-voltage and over-current transients.
With the addition of the ACPL-K370/K376 series, Avago can offer another
SSO-8 package option in addition to existing DIP packages to provide
customers with more optocoupler options for higher voltage industrial
applications. The ACPL-K376 is a low-current version of the ACPL-K370.
To obtain lower current operation, the ACPL-K376 uses a high-efficiency
aluminum gallium arsenide (AIGaAs) LED which provides higher light
output at lower drive currents.
