FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
H0EN — H0 Input 2pin Hall-effect Sensor Enable Bit
This read/write bit enables the 2-pin Hall-effect sensor
sense circuitry. Reset clears the H0EN bit.
1 = Hallport H0 is switched on and sensed
0 = Hallport H0 disabled
H0PD — Hallport Pull-up Disable Bit
This read/write bit disables the H0 pull-up resistor. Reset
clears the H0PD bit.
1 = Hallport pull-up resistor on H0 disabled
0 = Hallport pull-up resistor on H0 enabled
H0MS — H0 Mode Select
These read/write bits select the mode of the H0 input.
Reset clears the H0MS bits.
1 = H0 is 2-pin hall sensor input
0 = H0 is general purpose input
Half-bridge Outputs
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
Active clamp on low side MOSFET
Figure 22. 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). The HBx_L and HBx_H
bits 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 is in PWM mode.
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.
