3 Description
The DRV5033-Q1 device is a chopper-stabilized Hall
Effect Sensor that offers a magnetic sensing solution
with superior sensitivity stability over temperature and
integrated protection features.
The DRV5033-Q1 responds the same to both
polarities of magnetic field direction. When the
applied magnetic flux density exceeds the BOP
threshold, the DRV5033-Q1 open-drain output goes
low. The output stays low until the field decreases to
less than BRP, and then the output goes to high
impedance. The output current sink capability is 30
mA. A wide operating voltage range from 2.7 to 38 V
with reverse polarity protection up to –22 V makes
the device suitable for a wide range of automotive
applications.
Internal protection functions are provided for reverse
supply conditions, load dump, and output short circuit
or over current.

7 Detailed Description
7.1 Overview
The DRV5033-Q1 device is a chopper-stabilized hall sensor with a digital omnipolar switch output for magnetic
sensing applications. The DRV5033-Q1 device can be powered with a supply voltage between 2.7 and 38 V, and
will survive –22 V reverse battery conditions continuously. Note that the DRV5033-Q1 device will not be
operating when about –22 to 2.4 V is applied to VCC (with respect to GND). In addition, the device can withstand
voltages up to 40 V for transient durations.
The field polarity is defined as follows: a south pole near the marked side of the package is a positive magnetic
field. A north pole near the marked side of the package is a negative magnetic field.
The omnipolar configuration allows the hall sensor to respond to either a south or north pole. A strong magnetic
field of either polarity will cause the output to pull low (operate point, BOP), and a weaker magnetic field will cause
the output to release (release point, BRP). Hysteresis is included in between the operate and release points, so
magnetic field noise will not trip the output accidentally.
An external pullup resistor is required on the OUT pin. The OUT pin can be pulled up to VCC, or to a different
voltage supply. This allows for easier interfacing with controller circuits.

7.3.2 Device Output
If the device is powered on with a magnetic field strength between BRP and BOP, then the device output is
indeterminate and can either be Hi-Z or Low. If the field strength is greater than BOP, then the output is pulled
low. If the field strength is less than BRP, then the output is released.

7.3.3 Power-On Time
After applying VCC to the DRV5033-Q1 device, ton must elapse before the OUT pin is valid. During the power-up
sequence, the output is Hi-Z. A pulse as shown in Figure 13 and Figure 14 occurs at the end of ton. This pulse
can allow the host processor to determine when the DRV5033-Q1 output is valid after startup. In Case 1
(Figure 13) and Case 2 (Figure 14), the output is defined assuming a constant magnetic field B > BOP and B <
BRP.

Feature Description (continued)
If the device is powered on with the magnetic field strength BRP < B < BOP, then the device output is
indeterminate and can either be Hi-Z or pulled low. During the power-up sequence, the output is held Hi-Z until
ton has elapsed. At the end of ton, a pulse is given on the OUT pin to indicate that ton has elapsed. After ton, if the
magnetic field changes such that BOP < B, the output is released. Case 3 (Figure 15) and Case 4 (Figure 16)
show examples of this behavior.

7.3.4 Output Stage
The DRV5033-Q1 output stage uses an open-drain NMOS, and it is rated to sink up to 30 mA of current. For
proper operation, calculate the value of the pullup resistor R1 using Equation 1.
Vref max
V min
d R1 d ref
30 mA
100 µA
(1)
The size of R1 is a tradeoff between the OUT rise time and the current when OUT is pulled low. A lower current
is generally better, however faster transitions and bandwidth require a smaller resistor for faster switching.
In addition, ensure that the value of R1 > 500 Ω to ensure the output driver can pull the OUT pin close to GND.
NOTE
Vref is not restricted to VCC. The allowable voltage range of this pin is specified in the
Absolute Maximum Ratings.

Feature Description (continued)
7.3.5 Protection Circuits
The DRV5033-Q1 device is fully protected against overcurrent and reverse-supply conditions.
7.3.5.1 Overcurrent Protection (OCP)
An analog current-limit circuit limits the current through the FET. The driver current is clamped to IOCP. During
this clamping, the rDS(on) of the output FET is increased from the nominal value.
7.3.5.2 Load Dump Protection
The DRV5033-Q1 device operates at DC VCC conditions up to 38 V nominally, and can additionally withstand
VCC = 40 V. No current-limiting series resistor is required for this protection.
7.3.5.3 Reverse Supply Protection
The DRV5033-Q1 device is protected in the event that the VCC pin and the GND pin are reversed (up to –22 V).
NOTE
In a reverse supply condition, the OUT pin reverse-current must not exceed the ratings
specified in the Absolute Maximum Ratings.

8.2.1.2.1 Configuration Example
In a 3.3-V system, 3.2 V ≤ Vref ≤ 3.4 V. Use Equation 3 to calculate the allowable range for R1.

For this design example, use Equation 4 to calculate the allowable range of R1.

3.2 V
d R1 d
30 mA
100 µA
(4)
Therefore:
113 Ω ≤ R1 ≤ 32 kΩ
(5)
After finding the allowable range of R1 (Equation 5), select a value between 500 Ω and 32 kΩ for R1.
Assuming a system bandwidth of 10 kHz, use Equation 6 to calculate the value of C2.

For this design example, use Equation 7 to calculate the value of C2.

2S u R1 u C2
(7)
An R1 value of 10 kΩ and a C2 value less than 820 pF satisfy the requirement for a 10-kHz system bandwidth.
A selection of R1 = 10 kΩ and C2 = 680 pF would cause a low-pass filter with a corner frequency of 23.4 kHz.

8.2.2.2 Detailed Design Procedure
When the open-drain output of the device is high-impedance, current through the path equals the ICC of the
device (approximately 3 mA).
When the output pulls low, a parallel current path is added, equal to VCC / (R1 + rDS(on)). Using 12 V and 1 kΩ,
the parallel current is approximately 12 mA, making the total current approximately 15 mA.
The local bypass capacitor C1 should be at least 0.1 µF, and a larger value if there is high inductance in the
power line interconnect.
9 Power Supply Recommendations
The DRV5033-Q1 device is designed to operate from an input voltage supply (VM) range between 2.7 and 38 V.
A 0.01-µF (minimum) ceramic capacitor rated for VCC must be placed as close to the DRV5033-Q1 device as
possible.

10 Layout
10.1 Layout Guidelines
The bypass capacitor should be placed near the DRV5033-Q1 device for efficient power delivery with minimal
inductance. The external pullup resistor should be placed near the microcontroller input to provide the most
stable voltage at the input; alternatively, an integrated pullup resistor within the GPIO of the microcontroller can
be used.
Generally, using PCB copper planes underneath the DRV5033-Q1 device has no effect on magnetic flux, and
does not interfere with device performance. This is because copper is not a ferromagnetic material. However, If
nearby system components contain iron or nickel, they may redirect magnetic flux in unpredictable ways.
