5.4.4
HiZ management
L6717 is able to manage HiZ both for internal driver and for external drivers through the
PWMx signals. When the controller needs to set HiZ state for a phase or section, it sets the
corresponding PWMx pin floating and, at the same time, turn OFF both HS and LS
MOSFETs by proper action of the corresponding embedded driver.
5.4.5
Hardware jumper override - V_FIX
VID0/V_FIX pin allows the device to operate in V_FIX mode.
Anytime L6717 is enabled it checks the pin VID0/V_FIX voltage level: pull up VID0/V_FIX to
3.3V to enter V_FIX mode.
When in V_FIX mode, both NB and CORE Section voltages are governed by the information
shown in Table 7.
Regardless of the state of VID1, the device will work in SVI mode and furthermore PWROK
logic level is ignored.
SVC and SVD are considered as static VID and the output voltage changes according to
their status. Dynamic SVC/SVD-change management is provided in this condition.
V_FIX mode is intended for system debug only.
Protection management differs in this case, see Section 8.1 for details.
