7 Detailed Description
7.1 Overview
The DRV5015-Q1 is a magnetic sensor with a digital output that latches the most recent pole measured. During
power-up, in the absence of an external magnetic field, the DRV5015A1-Q1 and DRV5015A2-Q1 default to a low
output state and the DRV5015A3-Q1 defaults to a high output state. Applying a south magnetic pole near the top
of the package causes the DRV5015A1-Q1 and DRV5015A2-Q1 output to drive low, whereas a north magnetic
pole causes this output to drive high. Applying a south magnetic pole near the top of the package causes the
DRV5015A3-Q1 output to drive high, whereas a north magnetic pole causes this output to drive low. The
absence of a magnetic field causes the output to continue to drive the current state, whether low or high.
The device integrates a Hall effect element, analog signal conditioning, offset cancellation circuits, amplifiers, and
comparators. These features provide stable performance across a wide temperature range and resistance to
mechanical stress.

图 14 shows the DRV5015-Q1 open-drain output structure. An open-drain output offers flexibility by enabling
system designers to interface to wide-range GPIO termination voltages. C1 represents the input capacitance of
the GPIO. R1 represents the pullup resistor connected to the termination voltage, VPULL-UP. The maximum
allowable value of VPULL_UP is 5.5 V. The value of R1 must be selected after proper considerations among the
system speed and the power dissipation through the pullup resistor.

Feature Description (接下页)
7.3.6 Propagation Delay
The DRV5015-Q1 samples the Hall element at a nominal sampling interval of every 16.67 µs to detect the
presence of a magnetic north or south pole. At each sampling point, the device takes the average of the current
sampled value and immediately preceding sampled value of the magnetic field. If this average value crosses the
BOP or BRP threshold, the device output changes to the corresponding state as defined by the Overview section.
图 17 shows the DRV5015A1-Q1 propagation delay analysis in the proximity of a magnetic south pole. The Hall
element of the DRV5015-Q1 experiences an increasing magnetic field as a magnetic south pole approaches
near the device. At time t2, the average magnetic field is (B2 + B1) / 2, which is below the BOP threshold of the
device. At time t3, the actual magnetic field has crossed the BOP threshold. However, the average (B3 + B2) / 2 is
still less than the BOP threshold. As such, the device waits for next sample time, t4, to start the output transition
through the analog signal chain. The propagation delay, td, is measured as the delay from the time the magnetic
field crosses the BOP threshold to the time output transitions.

8 Application and Implementation
注
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The DRV5015-Q1 is ideal for use in rotary applications for brushless DC (BLDC) motor sensors or incremental
rotary encoding.
For reliable functionality, the magnet must apply a flux density at the sensor greater than the corresponding
maximum BOP or BRP numbers specified in the table. Add additional margin to account for mechanical tolerance,
temperature effects, and magnet variation. Magnets generally produce weaker fields as temperature increases.

8.2.1.2 Detailed Design Procedure
Three-phase brushless DC motors often use three Hall effect latch devices to measure the electrical angle of the
rotor and tell the controller how to drive the three wires. These wires connect to electromagnet windings, which
generate magnetic fields that apply forces to the permanent magnets on the rotor.
Space the three Hall sensors across the printed-circuit board (PCB) so that these sensors are 120 electrical
degrees apart. This configuration creates six 3-bit states with equal time duration for each electrical cycle, which
consists of one north and one south magnetic pole. From the center of the motor axis, the number of degrees to
space each sensor equals 2 / [number of poles] × 120°. In this design example, the first sensor is placed at 0°,
the second sensor is placed 20° rotated, and the third sensor is placed 40° rotated. Alternatively, a 3× degree
offset can be added or subtracted to any sensor, meaning that the third sensor can alternatively be placed at
40° – (3 × 20°) = –20°.

8.2.2.2 Detailed Design Procedure
Incremental encoders are used on knobs, wheels, motors, and flow meters to measure relative rotary movement.
By attaching a ring magnet to the rotating component and placing a DRV5015-Q1 nearby, the sensor generates
voltage pulses as the magnet turns. If directional information is also needed (clockwise versus counterclockwise),
a second DRV5015-Q1 can be added with a phase offset, and then the order of transitions between the two
signals describes the direction.
Creating this phase offset requires spacing the two sensors apart on the PCB, and an ideal 90° quadrature offset
is attained when the sensors are separated by half the length of each magnet pole, plus any integer number of
pole lengths. 图 20 shows this configuration because the sensors are 1.5 pole lengths apart. One of the sensors
changes its output every 360° / 8 poles / 2 sensors = 22.5° of rotation. For reference, the TIDA-00480 TI Design
Considerations Automotive Hall Sensor Rotary Encoder uses a 66-pole magnet with changes every 2.7°.
The maximum rotational speed that can be measured is limited by the sensor bandwidth. Generally, the
bandwidth must be faster than two times the number of poles per second. In this design example, the maximum
speed is 45000 RPM, which involves 6000 poles per second. The DRV5015-Q1 sensing bandwidth is typically
30 kHz, which is five times the pole frequency. In systems where the sensor sampling rate is close to two times
the number of poles per second, most of the samples measure a magnetic field that is significantly lower than the
peak value, because the peaks only occur when the sensor and pole are perfectly aligned. In this case, add
margin by applying a stronger magnetic field that has peaks significantly higher than the maximum BOP

8.3 What to Do and What Not to Do
The Hall element is sensitive to magnetic fields that are perpendicular to the top of the package; therefore, the
correct magnet orientation must be used for the sensor to detect the field. 图 22 shows correct and incorrect
orientations when using a ring magnet.

9 Power Supply Recommendations
The DRV5015-Q1 is powered from 2.5-V to 5.5-V DC power supplies. A decoupling capacitor close to the device
must be used to provide local energy with minimal inductance. TI recommends using a ceramic capacitor with a
value of at least 0.01 µF.
10 Layout
10.1 Layout Guidelines
Magnetic fields pass through most nonferromagnetic materials with no significant disturbance. Embedding Hall
effect sensors within plastic or aluminum enclosures and sensing magnets on the outside is common practice.
Magnetic fields also easily pass through most PCBs, which makes placing the magnet on the opposite side of
the PCB possible.
