GENERAL DESCRIPTION
MA7212 is integrated Hall sensors with output drivers, mainly designed for electronic
commutation of brush-less DC Fan. This IC is using HV BCD process internally includes the
regulator, protecting diode, Hall plate, amplifier, comparator, and a pair of complementary
open-Drain outputs (DO, DOB).
To avoid coil burning, rotor-lock shutdown detection circuit shut down the output driver if
the rotor is blocked and then the automatic recovery circuit will try to restart the motor. This
function repeats while rotor is blocked. Until the blocking is removed, the motor recovers
running normally.
FEATURES
- Built-in protecting diode only for chip reverse power connecting
- Wide operating voltage range: 2.5V~18V
- Output sink current up to 0.6A
- On-Chip High sensitivity Hall-effect Sensor
- Thermal Shutdown Protection
- -40°C to 85°C Operating Temperature
- Rotor-locked shutdown and automatically restart function
- For 5V and 12V DC motor / FAN systems
- Low Profile SIP-4L Package
