FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
HALF-BRIDGES
Outputs HB1:HB4 provide four low-resistive half-bridge
output stages. The half-bridges can be used in H-Bridge, high
side, or low side configurations.
Reset clears all bits in the H-Bridge output register
(HBOUT) owing to the fact that all half-bridge outputs are
switched off.
HB1:HB4 output features:
Short-circuit (over-current) protection on high side and
low side MOSFETs
Current recopy feature (low side MOSFET)
Over-temperature protection
Over-voltage and under-voltage protection
Current limitation feature (low side MOSFET)

HALF-BRIDGE CONTROL
Each output MOSFET can be controlled individually. The
general enable of the circuitry is done by setting PSON in the
system control register (SYSCTL). HBx_L and HBx_H form
one half-bridge. It is not possible to switch on both MOSFETs
in one half-bridge at the same time. If both bits are set, the
high-side MOSFET has a higher priority.
To avoid both MOSFETs (high side and low side) of one
half-bridge being on at the same time, a break-before-make
circuit exists. Switching the high side MOSFET on is inhibited
as long as the potential between gate and VSS is not below a
certain threshold. Switching the low side MOSFET on is
blocked as long as the potential between gate and source of
the high-side MOSFET did not fall below a certain threshold.
HALF-BRIDGE OUTPUT REGISTER (HBOUT)
Low Side On/Off Bits (HBx_L)
These read/write bits turn on the low side MOSFETs.
Reset clears the HBx_L bits.
1 = Low side MOSFET turned on for half-bridge output x
0 = Low side MOSFET turned off for half-bridge output x
