BLDC Vibration Motor Driver
3 Glossary of Terms
BLDC
Full Bridge (H-Bridge)
MilliTesla (mT), Gauss
Freewheel
Dead Point
Brush-Less Direct Current
Two push-pull output drivers enabling bidirectional current flow through the
connected load
Units of magnetic flux density:
1mT = 10 Gauss
Period of time while the rotor continues spinning after disengagement from the
drive mechanism, i.e. after switching off the coil output drivers in a BLDC motor.
Rotor angular position where the motor torque is zero

Note 1: Value of continuous output current using recommended land pattern – Exposed pad connected to PCB substrate with solder
Note 2: Human Body Model according JESD22-A114 standard – 100pF capacitor discharged through 1.5kΩ resistor into each pin.
Exceeding the absolute maximum ratings may cause permanent damage. Exposure to absolute-maximum-
rated conditions for extended periods may affect device reliability.
