FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
Overtemperature protection.
Overvoltage and undervoltage protection.
Current limitation feature (low side MOSFET).
Figure 11. Half-Bridge Push-Pull Output Driver
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.
HBx_H — High-Side On/Off Bits
These read write bits turn on the high-side MOSFETs.
Reset clears the HBx_H bits.
1 = High-side MOSFET turned on for half-bridge output
x.
