Bits 10, 11
With these bits it is possible to detect the status of the gate voltages of the lower output-
stage transistors T3 and T4. Bit 10: status for EN edge transition. Bit 11: whether the
lower transistor has at all been turned on.
Bit 12 indicates whether the nominal/actual comparator has switched. The comparator
switches when the output current is regulated.
Bits 13, 14, 15
These bits indicate the presence of overcurrent, undervoltage or overtemperature. A
fault is ORed and output direct by bit 0 on DI.
When the multiplexer is read out, bits 0 through 15 are output once non-inverted (Phase
= Low) and once inverted (Phase = High).
Bit Assignment in Error Register
Bit 0
=
High for overtemperature/undervoltage/overcurrent
Bit 1
=
always High
Bit 2
=
High when sink transistor Q1 turned on
Bit 3
=
High when sink transistor Q2 turned on
Bit 4
=
High when source transistor Q1 turned on
Bit 5
=
High when source transistor Q2 turned on
Bits 2-5 =
momentary states for readout
Bit 6
=
bit 2 state for falling edge of Enable signal
Bit 7
=
bit 3 state for falling edge of Enable signal
Bit 8
=
bit 4 state for falling edge of Enable signal
Bit 9
=
bit 5 state for falling edge of Enable signal
Bits 6-10
represent status of outputs for negative change in edge of Enable signal
Bit 11
=
High if gate-source voltage of sink transistors is > 5 V at moment of readout
Bits 11-15
are set if event occurs during switching (Enable = High)
Bit 11
=
High if sink transistor V
GS > 5 V
Bit 12
=
High if actual current lower than nominal current
Bit 13
=
High if overcurrent detected on source transistors
Bit 14
=
High if undervoltage detected
Bit 15
=
High if thermal link tripped
The memories are erased by a rising edge on the Enable input.
