Abstract MLX80153
OTP Full Bridge motor controller
7 Application Schematic example
NOTE: Shown schematics are reference examples that give a realistic indication of typical external components. In
actual applications additional components may be required, and component values will have to be revised.
7.1 Basic pump / fan example
 Double charge pump allows controlling HS NFETs under low battery conditions.
 High side NFET VDS monitoring (programmable voltage levels and blanking time)
protects for short circuits to ground.
 Phase voltage (BEMF) can be measured back via the phase pin.
 Applied Motor voltage is measured directly on the FET drains via VDRAIN pin.
 IC can wake up from either a falling or rising edge on one of its High Voltage inputs.
