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 (overcurrent) protection on high-side and low-
side MOSFETs.
Current recopy feature (low side MOSFET).
Overtemperature protection.
Overvoltage and undervoltage 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 V
SS
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)
HBx_L—Low-Side On/Off Bits
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.
