OM9373 International Rectifier Corp., OM9373 Datasheet - Page 13

• Manufacturer Part Number: OM9373
• Description: Full-featured Power Module For Direct Drive Of 3-phase Brushless Dc Motor F-43 / Mp3-43l Packages
• Manufacturer: International Rectifier Corp.

Table 1 shows the Phase Output state versus the state
of the Hall-Effect and Direction Inputs. Please note
that the OM9373 Hall-Effect Inputs are Grey-encoded;
that is, only one input is allowed to change from one
input state to another at a time.

Package and Screening Options
The OM9373 is offered in F-43, a hermetic flatpack
package as well as in MP3-43L, a plastic ring frame,
low profile flatpack package.
The hermetic version is offered in two standard
screening levels: a full military temperature range of
-55°C to +125°C with limited screening and with

The screening levels for the SFB, SFP and SPP
versions are listed in the table below. All tests and
inspections are in accordance with those listed in
MIL-STD-883.
The commutation coding shown reflects Hall-Effect
sensors that are spaced at 120° mechanical
increments. Also, internal protection logic disables
all three Phase Outputs when the Hall-Effect Inputs
are set to an illegal condition (i.e. all logic low or all
logic high).
