HALF-BRIDGE OVERTEMPERATURE
PROTECTION
The half-bridge outputs provide an overtemperature
prewarning with the HTF in the Interrupt Flag Register (IFR).
In order to protect the outputs against overtemperature, the
High Temperature Reset must be enabled. If this value is
reached, the part generates a reset and disables all power
outputs.
HALF-BRIDGE OVERCURRENT PROTECTION
The half-bridges are protected against short to GND, short
to VSUP, and load shorts.
In the event an overcurrent on the high side is detected,
the high side MOSFETs on all HB high side MOSFETs are
switched off automatically. In the event an overcurrent on the
low side is detected, all HB low side MOSFETs are switched
off automatically. In both cases, the overcurrent status flag
HB_OCF in the System Status Register (SYSSTAT) is set.
The overcurrent status flag is cleared (and the outputs re-
enabled) by writing a logic [1] to the HB_OCF flag in the
System Status Register or by reset.
HALF-BRIDGE OVERVOLTAGE/UNDERVOLTAGE
The half-bridge outputs are protected against
undervoltage and overvoltage conditions. This protection is
done by the low and high voltage interrupt circuitry. If one of
these flags (LVF, HVF) is set, the outputs are automatically
disabled.
The overvoltage/undervoltage status flags are cleared
(and the outputs re-enabled) by writing a logic [1] to the LVF/
HVF flags in the Interrupt Flag Register or by reset. Clearing
this flag is useless as long as a high or low voltage condition
is present.
Half-bridge Control Register (HBCTL)
OFC_EN—H-bridge Offset Chopping Enable Bit
This read/write bit enables offset chopping. Reset clears
the OFC_EN bit.
1 = Offset chopping enabled.
0 = Offset chopping disabled.
CSA—H-bridges Current Sense Amplification Select Bit
This read/write bit selects the current sense amplification
of the H-bridges. Reset clears the CSA bit.
