Texas Instruments DRV5053RAQLPGM

Overview

DRV5053RAQLPGM from Texas Instruments is a chopper-stabilized analog bipolar Hall effect sensor in TO-92 (LPG) package, delivering –45 mV/mT sensitivity, 0.2–1.8 V linear output voltage range, and operation from 2.5 V to 38 V supply across –40°C to +125°C ambient. It distinguishes magnetic polarity with 1 V quiescent output at B = 0 mT and supports flow metering, damper control, and vibration correction systems.

For engineers reviewing the DRV5053RAQLPGM datasheet, DRV5053RAQLPGM pinout, DRV5053RAQLPGM application, or DRV5053RAQLPGM equivalent, key selection criteria include its –45 mV/mT sensitivity grade, TO-92 through-hole package footprint (4.00 mm × 3.15 mm), reverse supply protection up to –22 V, 35 µs power-on time, and ±10% sensitivity stability over temperature.

Technical Context

The DRV5053RAQLPGM implements chopper stabilization to suppress offset drift and achieve superior temperature stability of sensitivity (±10% over –40°C to +125°C). Its analog output stage provides 300 µA source / 2.3 mA sink capability with 20 kHz bandwidth and <0.79 mTpp input-referred noise.

This variant (RA) is calibrated for –45 mV/mT sensitivity, enabling high-resolution detection of weak magnetic fields down to ±18 mT saturation limits at 3.3 V supply. The device enters inactive state under reverse supply (–22 V to 2.4 V) and withstands transient 40 V load dump without external protection.

FAQ

What is the sensitivity specification of the DRV5053RAQLPGM?

The DRV5053RAQLPGM has a nominal sensitivity of –45 mV/mT, meaning its output voltage decreases by 45 mV per millitesla increase in magnetic flux density applied perpendicular to the marked side of the TO-92 package. This value is specified over –40°C to +125°C ambient and exhibits ±10% variation across that range, as confirmed in the electrical characteristics table of the SLIS153D datasheet.

Does the DRV5053RAQLPGM support reverse battery protection?

Yes, the DRV5053RAQLPGM supports reverse supply protection up to –22 V continuously, as stated in Section 6.1 Absolute Maximum Ratings. During reverse bias (–22 V to 2.4 V on VCC), the device is disabled but remains undamaged. Recovery occurs automatically once VCC returns to ≥2.5 V, making it suitable for automotive and mobile equipment with unregulated power inputs.

What package type does the DRV5053RAQLPGM use, and what are its dimensions?

The DRV5053RAQLPGM uses a 3-pin TO-92 (LPG) through-hole package with nominal body dimensions of 4.00 mm × 3.15 mm, as documented in the Package Information table and Mechanical, Packaging, and Orderable Information section. This package offers mechanical robustness and thermal performance advantageous for high-vibration applications such as damper controls and industrial actuators.

How does the output polarity of the DRV5053RAQLPGM respond to magnetic field direction?

The DRV5053RAQLPGM outputs 1.0 V at zero magnetic field. With its –45 mV/mT sensitivity, a south pole near the marked side of the package reduces the output below 1.0 V, while a north pole increases it above 1.0 V. This polarity behavior is defined in Section 7.3.2 and Figure 7-2 of the datasheet, and applies consistently across the full operating temperature range.

What is the maximum allowable capacitive load on the DRV5053RAQLPGM output pin?

The DRV5053RAQLPGM output pin supports a maximum capacitive load of 10 nF to ensure amplifier stability, as specified in Section 7.3.4 Output Stage. Exceeding this limit may cause oscillation or slow settling. For noise reduction, an external RC filter with R ≥ 200 Ω and C ≤ 0.1 µF is acceptable, provided the total capacitance-including PCB trace and MCU input-remains within the 10 nF limit.
