Description
High voltage supply (12V-60V)
Logic supply (5V)
Half bridge output
Half bridge output
Half bridge output
Power ground, high current ground return path of the bridge outputs
Analog and logic circuits ground
Disable logic Input, CMOS. When high disables all six output MOSFETs independent of the Control regis-
ters.
Output pin goes high at Tj > 135°C.
The Fault output is raised under the following conditions:
a) Short-Circuit and Over Current condition.
b) High Temperature condition.
c) High Voltage Supply Vs < 12V.
This can be used as an interrupt to the microcontroller. It will be reset after status data has been read by
the microcontroller. A FAULT will also disable the outputs of the device.
goes high in order to indicate the Pchannel of output A is to be turned on.
goes high in order to indicate the Nchannel of output A is to be turned on.
goes high in order to indicate the Pchannel of output B is to be turned on.
goes high in order to indicate the Nchannel of output B is to be turned on.
goes high in order to indicate the Pchannel of output C is to be turned on.
goes high in order to indicate the Nchannel of output C is to be turned on.
Current monitor output, approximate current 1/4000 of Phase A current
Current monitor output, approximate current 1/3600 of Phase B current
Current monitor output, approximate current 1/3700 of Phase C current
Disables all Fault Mechanisms when pulled HIGH
