ACNU-4803
Inverted Logic High CMR Intelligent Power
Module (IPM) and Gate Drive Interface
Optocoupler
Data Sheet
Description
The Broadcom® ACNU-4803 is a single-channel fast-speed
optocoupler in SSO8 footprint. It contains a AlGaAs LED
and photo detector with a built-in Schmitt trigger to provide
logic compatible waveforms, eliminating the need for
additional wave shaping. The totem pole output eliminates
the need for a pull-up resistor and allows for direct drive
intelligent power modules. Minimized propagation delay
differences between devices makes these optocouplers
excellent solutions for improving inverter efficiency through
reduced switching dead times.
The ACNU-4803 is suitable for IPM interface isolation, AC
and brushless DC motor drives, industrial inverters and
space-constrained industrial applications. This SSO8
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.
