5.2.4
The TLE7183F has an integrated undervoltage shut down, to assure that the behavior of the device is predictable
in all supply voltage ranges.
If the voltage of a charge pump buffer capacitors CBx reaches the undervoltage shut down level for a minimum
specified filter time, the gate-source voltage of all external MOSFETs will be actively pulled to low. In this situation
the short circuit detection of this output stage is deactivated to avoid a latching shut down of the driver.
As soon as the charge pump buffer voltage recovers, the output stage condition will be aligned to the input patterns
automatically. This allows to continue operation of the motor in case of undervoltage shut down without a reset by
the µC.
Undervoltage shut down will not occur when V
capacitors Cxx = 4.7 µF.
5.2.5
The TLE7183F has an integrated overvoltage shut down to avoid destruction of the IC at high supply voltages.
The voltage is observed at the Vs and the VDH pin. When one of them or all of them exceed the overvoltage shut
down level for more than the specified filter time then the external MOSFETs are switched off. In addition,
overvoltage will shut down the charge pumps and will discharge the charge pump capacitors. This results in an
undervoltage condition which will be indicated on the ERRx pins. During overvoltage shut down the external
MOSFETs and the charge pumps remain off until a reset is performed.
5.2.6
If the junction temperature is exceeding typ. 170°C an error signal is given as warning. The driver IC will continue
to operate in order not to disturb the application.
The warning is removed automatically when the junction temperature is cooling down.It is in the responsibility of
the user to protect the device against overtemperature destruction.
5.2.7
The TLE7183F has two status pins to provide diagnostic feedback to the µC. The outputs of these pins are 5V
push pull stages, they are either high or low.
