Texas Instruments DRV2510QPWPRQ1

Overview

DRV2510QPWPRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive haptic driver IC designed for solenoid and voice-coil actuators, delivering 3-A peak current via a low-R_DS(on) full H-bridge (180 mΩ), operating from 4.5 V to 18 V, with integrated ISO-7637-2-compliant 40-V load-dump protection and real-time diagnostics for open/short-load detection.

For engineers reviewing the DRV2510QPWPRQ1 datasheet, DRV2510QPWPRQ1 pinout, DRV2510QPWPRQ1 application, or DRV2510QPWPRQ1 equivalent, this page delivers verified electrical specs, thermal metrics, I²C register-mapped diagnostics, fault reporting behavior, and automotive-grade protection thresholds - all confirmed against TI's SLOS919D production datasheet (Nov 2023).

Technical Context

The DRV2510QPWPRQ1 implements a BD-mode PWM architecture with 400-kHz switching frequency, enabling low-noise, low-distortion actuator drive while minimizing I²R losses through differential output phasing. Its analog front-end supports configurable gain (20–36 dB) via I²C and rejects common-mode noise with 63-dB CMRR at 1 kHz.

Protection is hardware- and firmware-coordinated: over-current (3.5-A trip), over-temperature (150°C junction), over-voltage (21-V trip), under-voltage (4-V lockout), and load diagnostics execute in <229 ms with Hi-Z output enforcement and dual-reporting via INTZ pin and I²C registers - all compliant with AEC-Q100 Grade 1 (–40°C to 125°C ambient).

Key Specifications

Pinout & Package

DRV2510QPWPRQ1 is housed in a thermally enhanced HTSSOP-16 (PWP) package measuring 5.00 mm × 4.40 mm, featuring an exposed thermal pad that must be connected to GND for optimal junction-to-board thermal performance (R_θJB = 20 °C/W).

Equivalent & Alternatives

The following parts are listed as comparable options for similar haptic driver applications.

Compared with DRV2510QPWPRQ1, DRV2605LRTVT offers lower integration for cost-sensitive consumer haptics but cannot replace it in automotive solenoid/voice-coil systems due to missing 3-A drive, load-dump protection, and AEC-Q100 compliance; TPS61165DRVR serves a completely different power-conversion function and is not a haptic driver alternative.

FAQ

What is the absolute maximum VDD rating for DRV2510QPWPRQ1?

The absolute maximum VDD rating for DRV2510QPWPRQ1 is 30 V for DC operation and 40 V for pulsed exposure (<400 ms), per Section 6.1 of the SLOS919D datasheet. This 40-V pulse rating directly supports ISO-7637-2 load-dump immunity without external clamping components. Exceeding these limits risks permanent damage, and operation above 18 V is not recommended for continuous use.

Does DRV2510QPWPRQ1 support differential analog input signals?

Yes, DRV2510QPWPRQ1 accepts true differential analog inputs on pins IN+ and IN−, with common-mode voltage range from 0.3 V to 4.4 V and 63-dB CMRR at 1 kHz. The input stage cancels noise coupled equally to both lines, making it robust in electrically noisy automotive environments. Gain is programmable via I²C (20–36 dB), and input impedance varies inversely with gain setting (e.g., 60 kΩ at 20 dB).

How does the load diagnostic function operate on DRV2510QPWPRQ1?

The load diagnostic function on DRV2510QPWPRQ1 executes automatically upon EN assertion or fault detection, completing in 229 ms using a four-phase sequence (discharge → ramp up → check → ramp down). It identifies open load, short-to-GND, short-to-VDD, and shorted-load conditions by biasing the outputs and measuring impedance. Results are reported via I²C register 0x0A and optionally asserted on the INTZ pin for critical faults.

What thermal performance can be expected from DRV2510QPWPRQ1 in a standard PCB layout?

In a standard 4-layer PCB with 2 oz copper and thermal pad soldered to a 1-in² GND plane, DRV2510QPWPRQ1 achieves R_θJB = 20 °C/W and R_θJA = 39.4 °C/W. At 3-A peak current and 12-V supply, typical power dissipation is ~1.1 W, resulting in ~22°C junction-to-ambient rise - well within the 150°C max junction limit. Layout guidelines in Section 10 of SLOS919D must be followed to maintain this performance.

Is DRV2510QPWPRQ1 pin-compatible with any other Texas Instruments haptic drivers?

No, DRV2510QPWPRQ1 is not pin-compatible with other TI haptic drivers such as DRV2605 or DRV2667. Its HTSSOP-16 pinout is unique, with dedicated BSTP/BSTN, REG, STDBY, and INTZ signals not found in legacy devices. Migration requires PCB redesign and firmware adaptation due to differences in I²C register map, diagnostic behavior, and protection thresholds.
