Figure 2. Overcurrent Control Timing
FUNCTIONAL DESCRIPTION
Device Operation
The DRV8800/DRV8801 is designed to drive one dc motor. The current through the output full-bridge switches
and all N-channel DMOS are regulated with a fixed off-time PWM control circuit.
Logic Inputs
It is recommended to use a high-value pullup resistor when logic inputs are pulled up to VDD. This resistor limits
the current to the input in case an overvoltage event occurs. Logic inputs are nSLEEP, MODE, PHASE, and
ENABLE. Voltages higher than 7 V on any logic input can cause damage to the input structure.
VREG (DRV8800 Only)
This output represents a measurement of the internal regulator voltage. This pin should be left disconnected. A
voltage of approximately 7.5 V can be measured at this pin.
VPROPI (DRV8801 Only)
This output offers an analog voltage proportional to the winding current. Voltage at this terminal is five times
greater than the motor winding current (VPROPI = 5×I). VPROPI is meaningful only if there is a resistor
connected to the SENSE pin. If SENSE is connected to ground, VPROPI measures 0 V. During slow decay,
VPROPI outputs 0 V. VPROPI can output a maximum of 2.5 V, since at 500 mV on SENSE, the H-bridge is
disabled.
