Failure Management
Any error detected will set the error latch and force the output PRIM_nERROR_OUT into HIGH state. Switching pulses from
the controller will be ignored. Connected and switched off IGBTs remain turned off. The switched off IGBTs remain turned
off. A reset of the latched error memory is only possible if no failure is present anymore and if the TOP and BOT input
signals are set to the LOW level for a period of tpERRRESET > 9µs.
The output PRIM_nERROR_OUT is an open collector output. For the error evaluation an external pull-up-resistor is
necessary pulled-up to the positive operation voltage of the control logic (LOW signal = no error present, wire break safety is
assured).

Application hints
An external resistor to the controller logic high level is required. The
resistor has to be in the range of V / Imax < Rpull_up < 10kΩ.
PRIM_nERROR_OUT can operate to maximum 30V and can switch
a maximum of 15mA.
Example:
For V = +15V the needed resistor should be in the range
Rpull_up = (15V/15mA) … 10kΩ ⇒ 1kΩ… 10kΩ.
Please note:
The error output PRIM_ERROR_OUT is not short circuit proof.
Shut Down Input (SDI)
The shut down input / error input signal can gather error signals of other hardware components for switching off the IGBT
(input HIGH = no turn-off; input LOW = turn-off).
A LOW signal at PRIM_nERROR_IN will set the error latch and force the output PRIM_nERROR_OUT into HIGH state.
Switching pulses from the controller will be ignored. A reset of the latched error memory is only possible if no LOW signal at
PRIM_nERROR_IN is present anymore and if the TOP and BOT input signals are set to the LOW level for a period of
tpERRRESET > 9µs.
The SDI function can be disabled by no connection or connecting to 5V.
