In the event of a shorted load, shorted winding, or stalled
motor, the load current will attempt to increase. As described
above, the drive current to the output stage is diverted
(limiting the load current to about 1 A), causing the output
stage to go linear. As the junction temperature of the output
stage increases, the thermal limiting circuit will become
operational, further decreasing the drive current. The load
current (junction temperature) is then a function of ambient
temperature, state of remaining drivers, supply voltage, and
load resistance. If the fault condition is corrected, the output
driver will return to its normal saturated condition.

The VMIVME-2511 is a VMEbus compatible programmable I/O board. It utilizes
two Motorola MC68230 Parallel InterfaceJTimer I.C.'s and one Motorola MC68153 Bus
Interrupter Module and has the following features:
48 Bits of I/O (bit 110, unidirectional 8-bit and 16-bit, bidirectional 8-bit and
16-bit)
Interrupt generation logic allowing four interrupt sources. One timer interrupt
and one port interrupt per MC68230
Optional high current drivers with 64mA sink capability (optional)
Two 24-bit programmable timers
Software programmable timer modes
Selectable handshake timer provides an interface flexible enough for
connection to a wide variety of low, medium or high speed peripherals or other
computer systems
Centronics Parallel Interface
PHYSICAL DESCRIPTION
The VMIVME-2511 Programmable I10 Board consists of VMEbus compatibility
logic, interrupt control logic, and I10 control logic associated with the parallel
interfaceltirner modules.
The VMEbus compatibility logic contains address decoding logic and data
transfer control logic allowing VMEbus write and read data transfers.
Interrupt control logic which utilizes the Motorola MC68153 BIM allows port and
timer interrupts from each parallel interfaceltimer. The interrupt requests to the CPU
are issued by the MC68153 when requested to do so by the parallel interfaceltimer
(68230).
