Analog Integrated Circuit Device Data
Freescale Semiconductor
This read/write bit enables the 2pin hall-effect sensor
This read/write bit disables the H0 Pull-up resistor.
These read/write bits select the mode of the H0 input
0 = Hallport sensed low / current above threshold
1 = Hallport H0 is switched on and sensed
0 = Hallport H0 disabled
1 = Hallport Pull-up resistor on H0 disabled
0 = Hallport Pull-up resistor on H0 enabled
1 = H0 is 2-pin hallsensor input

output stages. The half-bridges can be used in H-Bridge,
high-side or low-side configurations.
(HBOUT) owing to the fact that all half-bridge outputs are
switched off.
Outputs HB1:HB4 provide four low-resistive half-bridge
Reset clears all bits in the H-Bridge Output Register
HB1:HB4 output features
• Short circuit (overcurrent) protection on high-side and
• Current recopy feature (low-side MOSFET)
• Overtemperature protection
• Overvoltage and undervoltage protection
• Active clamp on low-side MOSFET
0 = H0 is general purpose input
