Product details
Overview
DRV5021A2EDBZRQ1 from Texas Instruments is an automotive-grade, unipolar digital-switch Hall effect sensor in SOT-23 package, operating from 2.5 V to 5.5 V, with magnetic operate point (BOP) of 9.2 mT and release point (BRP) of 7.0 mT at –40°C to +125°C, delivering open-drain output capable of 20 mA sinking for gear shifter position detection in automotive body control modules.
For engineers reviewing the DRV5021A2EDBZRQ1 datasheet, DRV5021A2EDBZRQ1 pinout, DRV5021A2EDBZRQ1 application, or DRV5021A2EDBZRQ1 equivalent, key selection considerations include its AEC-Q100 Grade 0 qualification (–40°C to +150°C), 30-kHz sensing bandwidth, integrated hysteresis (2.2 mT typ), SOT-23 footprint compatibility, and requirement for external pullup resistor on the open-drain output.
Technical Context
The DRV5021A2EDBZRQ1 implements a spinning-current Hall element with analog signal conditioning, offset cancellation, and temperature compensation to deliver stable magnetic threshold performance across –40°C to +150°C ambient. Its digital output stage uses an NMOS open-drain driver rated for 20 mA sink current and 0.4 V max VOL at 20 mA.
It operates exclusively in unipolar mode: output pulls low when perpendicular magnetic flux density exceeds BOP (9.2 mT), releases to high-impedance when flux falls below BRP (7.0 mT), with propagation delay ≤25 µs and power-on time ≤70 µs. Hysteresis (|BOP – BRP| = 2.2 mT typ) prevents noise-induced toggling near thresholds.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV5021A1EDBZRQ1 | BOP/BRP = 2.9 mT / 1.8 mT - lower sensitivity, narrower hysteresis (1.1 mT typ) | Better suited for weak-field or close-proximity detection (e.g., small magnets, thin air gaps) | Select when target field strength is <5 mT; avoid in high-noise environments requiring larger hysteresis |
| DRV5021A3EDBZRQ1 | BOP/BRP = 17.9 mT / 14.1 mT - higher sensitivity, wider hysteresis (3.8 mT typ) | Required for large air gaps, shielded environments, or strong-field interference mitigation | Choose when magnet distance exceeds 3 mm or system EMI is severe; verify field strength exceeds 14 mT at release point |

FAQ
What is the magnetic sensitivity specification for DRV5021A2EDBZRQ1?
The DRV5021A2EDBZRQ1 has a magnetic operate point (BOP) of 9.2 mT and release point (BRP) of 7.0 mT at –40°C to +125°C, with hysteresis (|BOP – BRP|) of 2.2 mT typical. These values are specified across the full automotive temperature range (–40°C to +150°C), with BOP ranging from 4.5 mT to 14.0 mT and BRP from 2.7 mT to 11.0 mT under extreme conditions. The DRV5021A2EDBZRQ1 is calibrated for unipolar south-pole activation only.
Does DRV5021A2EDBZRQ1 require an external pullup resistor?
Yes, DRV5021A2EDBZRQ1 features an open-drain NMOS output that requires an external pullup resistor on the OUT pin. The recommended value ranges from 500 Ω to 32 kΩ depending on system voltage and rise-time requirements. A 10 kΩ resistor is commonly used with 3.3 V or 5 V controllers. The pullup may connect to VCC or another logic rail within the 0–5.5 V output voltage rating.
What is the maximum operating temperature for DRV5021A2EDBZRQ1?
The DRV5021A2EDBZRQ1 is qualified per AEC-Q100 Grade 0 with an ambient operating temperature range of –40°C to +150°C. Its junction temperature can reach up to +170°C under maximum power dissipation. Thermal resistance (RθJA) is 356°C/W in the SOT-23 (DBZ) package, so proper PCB copper area and layout are essential to maintain reliability at high ambient temperatures.
Can DRV5021A2EDBZRQ1 be used in two-wire configurations?
Yes, DRV5021A2EDBZRQ1 supports two-wire operation by connecting the OUT pin to VCC through a current-sense resistor. When inactive (high-impedance), total supply current is ~2.3 mA (ICC). When active (output pulled low), current increases by ~5 mA (VCC / R1 + rDS(on)), enabling detection via current monitoring instead of voltage level - useful in space-constrained wiring harnesses.
Is DRV5021A2EDBZRQ1 pin-compatible with other variants in the DRV5021-Q1 family?
Yes, all DRV5021-Q1 variants - including DRV5021A1EDBZRQ1, DRV5021A2EDBZRQ1, and DRV5021A3EDBZRQ1 - share identical SOT-23 (DBZ) 3-pin packaging, pinout (VCC–OUT–GND), and electrical interface. They differ only in magnetic sensitivity thresholds and are drop-in replacements for layout and schematic reuse, provided the application's field strength matches the selected variant's BOP/BRP range.
