3. If a VREG Under Voltage Shut Down occurs and no Over Temperature Prewarning is present, the device will
4. If VDD Under Voltage Shut Down occurs or a VREG Under Voltage Shut Down together with a Over
5. If one or more of the following errors occur, the device goes to the Error Mode: VREG Under Voltage Shut
Go-To-Sleep Mode
The Go-To-Sleep Mode can be reached in 2 different ways:
1. The device is in Normal Mode and RGS is set to low for a time longer than
2. The device is in VREG Shut-down Mode and RGS is set to low for a time longer than
In this mode all external MOSFETs are actively or passively switched off. An Error is set and is shown as long as
VDD is sufficient high. In this mode VDD and VREG is switched off. As soon as VDD voltage reaches the
level the IC goes into the Sleep Mode.
Normal Mode with Over Temperature Prewarning
This mode can be reached in 2 different ways:
1. The device is in Error Mode, the chip temperature is above the prewarning level while a reset is performed by
2. The device is in Normal Mode and the chip temperature increases above the prewarning level.
In this mode all functions are active and available. The gate drive output stages can be controlled with the input
pins with the regular limitations of the bootstrap principle.
The ERR pin is set to low and is latched.
There are 3 possibilities to leave this mode:
1. This mode can be left into the Normal Mode by applying a reset at RGS if the temperature has dropped below
2. The device goes into Error Mode if one of the following errors occurs: VREG Under Voltage Shut Down, VDD
3. The device goes into Deadlock Mode if either a VREG Under Voltage Shut Down or a VDD Under Voltage Shut
If the temperature is still in the pre-warning range and RGS is low, the ERR pin gets high only during the time were
RGS is low and the IC stays in the “Normal Mode with Over Temperature Prewarning”.
Deadlock Mode
This mode is intended to prevent the IC for long time toggling in Over Temperature if a short is present at the VDD
pin.
There are 4 ways to enter this mode:
1. The IC is in Error Mode and a VDD Under Voltage Shut Down occurs or a VREG Under Voltage Shut Down
2. The IC is in Normal Mode with Over Temperature Prewarning and a VDD Under Voltage Shut Down or a VREG
3. The IC is in Normal Mode and a VDD Under Voltage Shut Down occurs or a VREG Under Voltage Shut Down
4. The IC is in VREG Shut Down Mode and a VDD Under Voltage Shut Down or a Over Temperature Prewarning
In this mode VDD and VREG are switched off. The gates of the external MOSFETs are passively clamped.
