APPLICATIONS INFORMATION
TYPICAL APPLICATION USAGE
The architecture of the ADuM6132 is ideal for motor drive and
inverter applications where the low-side channels are common
to the controller. This arrangement requires only two isolation
regions in a package. All the isolated signals and the isolated
power are grouped on one side of the package to maintain full
package creepage and clearance. The low-side driver, as well as the
control signals, share a common reference and are also grouped.
To maximize the effectiveness of external bypass capacitors, the
isoPower dc-to-dc converter is not internally tied to the data
channels, and should be treated as a completely independent
subsystem, except for a UVLO function (see the Undervoltage
Lockout section). This means that power must be applied to V
to operate the dc-to-dc converter. Power must also be applied to
V
driver output. On the secondary side, the power generated at

The ADuM6132 is intended for use in driving low gate
capacitance transistors (200 pF typically). Most high voltage
applications involve larger transistors than this. To accom-
modate these applications, users can implement a buffer
configuration with the ADuM6132, as shown in Figure 16. In
many cases, this buffer configuration is the least expensive
option to drive high capacitance devices and provides the
greatest amount of design flexibility. The precise buffer/high

PCB LAYOUT
The ADuM6132 digital isolator with integrated 275 mW
isoPower dc-to-dc converter requires no external interface
circuitry for the logic interfaces. Power supply bypassing is
required at the input and output supply pins (see Figure 17).
The power supply section of the ADuM6132 uses a very high
oscillator frequency to efficiently pass power through its chip
scale transformers. In addition, the normal operation of the
data section of the iCoupler introduces switching transients
on the power supply pins. Bypass capacitors are required for
several operating frequencies. Noise suppression requires a low
ESR, high frequency capacitor; ripple suppression and proper
regulation require a large value capacitor in parallel (see Table 10).
The total lead length between both ends of the capacitor and
the input power supply pin should not exceed 20 mm.
