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.
