3 Description
The DRV5023 device is a chopper-stabilized Hall
Effect Sensor that offers a magnetic sensing solution
with superior sensitivity stability over temperature and
integrated protection features.
When the applied magnetic flux density exceeds the
BOP threshold, the DRV5023 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 2.5 to 38 V
with reverse polarity protection up to –22 V makes
the device suitable for a wide range of industrial
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 DRV5023 device is a chopper-stabilized Hall sensor with a digital output for magnetic sensing applications.
The DRV5023 device can be powered with a supply voltage between 2.5 and 38 V, and will survive –22 V
reverse-battery conditions. The DRV5023 device does not operate when –22 to 2.4 V is applied to the VCC pin
(with respect to GND pin). In addition, the device can withstand supply 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 output state is dependent on the magnetic field perpendicular to the package. A strong south pole near the
marked side of the package causes the output to pull low (operate point, BOP), and a weak south pole causes
the output to release (release point, BRP). Hysteresis is included in between the operate point and the release
point therefore magnetic-field noise does not accidentally trip the output.
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. For the FA, AJ, and BI device versions, 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.
For the FI device version, if the field strength is greater than BOP, then the output is Hi-Z; if the field strength is
less than BRP, then the output is pulled Low.

Feature Description (continued)
7.3.3 Power-On Time
After applying VCC to the DRV5023 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 DRV5023 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 DRV5023 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

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.

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 DRV5023 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 DRV5023 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 DRV5023 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.

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.

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 DRV5023 device is designed to operate from an input voltage supply (VM) range between 2.5 and 38 V. A
0.01-µF (minimum) ceramic capacitor rated for VCC must be placed as close to the DRV5023 device as possible.

10 Layout
10.1 Layout Guidelines
The bypass capacitor should be placed near the DRV5023 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 DRV5023 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.
