(6) Thermal Shutdown Flag Output Function
TSDM = Hi-Z (normal operation)
When thermal shutdown is activated, TSDM terminal becomes Low, all driver outputs (VO1-VO5) and regulator
outputs (REG5, REGVAR) are turned OFF (output Hi-Z).

(7) Power Supply Drop Mute and VC Drop Mute Function
Power supply drop mute functions at VPREVCC<VMPREVCC(3.8V Typ). At this condition all driver outputs (VO1-VO5)
are turned OFF (output Hi-Z).
VC drop mute functions at VVCO<VMVCO(0.7V Typ). At this condition driver outputs (VO1-VO4) also are turned OFF
(output Hi-Z).
