FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
Figure 20. BEMF Signal Generation
HALF-BRIDGE OVER-TEMPERATURE
PROTECTION
The half-bridge outputs provide an over-temperature pre-
warning with the HTF in the Interrupt Flag Register (IFR). In
order to protect the outputs against over-temperature, the
high temperature reset must be enabled. If this value is
reached, the part generates a reset and disables all power
outputs.
HALF-BRIDGE OVER-CURRENT PROTECTION
The half-bridges are protected against short to GND, short
to VSUP, and load shorts.
In the event an over-current on the high side is detected,
the high side MOSFETs on all HB high side MOSFETs are
switched off automatically. In the event an over-current on the
low side is detected, all HB low side MOSFETs are switched
off automatically. In both cases the over-current status flag
HB_OCF in the system status register (SYSSTAT) is set.
The over-current 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 OVER-VOLTAGE/UNDER-
VOLTAGE
The half-bridge outputs are protected against under-
voltage and over-voltage 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 over-voltage/under-voltage 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)
H-Bridge Offset Chopping Enable Bit (OFC_EN)
This read/write bit enables offset chopping. Reset clears
the OFC_EN bit.
1 = Offset chopping enabled
0 = Offset chopping disabled
H-Bridges Current Sense Amplification Select Bit (CSA)
This read/write bit selects the current sense amplification
of the H-Bridges. Reset clears the CSA bit.
1 = Current sense amplification set for measuring 0.5 A.
0 = Current sense amplification set for measuring 2.5 A.
