Product details
Overview
DRV2625YFFT from Texas Instruments is an ultra-low-power closed-loop haptic driver supporting both LRA and ERM actuators, featuring automatic resonance tracking (±1 Hz resolution), 1.55 µA standby current at 3.6 V, I²C-controlled playback engine, and integrated Immersion TouchSense® 2200 waveform library - deployed in mobile touch feedback and wearable device alerts.
For engineers reviewing the DRV2625YFFT datasheet, DRV2625YFFT pinout, DRV2625YFFT application, or DRV2625YFFT equivalent, key selection criteria include closed-loop LRA frequency range (45–300 Hz), 9-pin DSBGA package (1.498 mm × 1.361 mm), shutdown current <180 nA, real-time playback (RTP) mode latency <1 ms, and resistance-based actuator diagnostics.
Technical Context
The DRV2625YFFT implements a proprietary smart-loop architecture with real-time back-EMF detection for automatic resonance tracking and level calibration. It supports dual-mode operation: closed-loop for precise LRA control (with auto-braking and overdrive) and configurable open-loop (sine/square waveforms, OL_LRA_PERIOD programmable).
Its I²C interface (400 kHz compliant) controls a 1 kB internal RAM waveform sequencer and integrates a 1.8 V regulator (REG pin), NRST-triggered shutdown, and TRIG/INTZ multi-function pin for hardware triggering or interrupt reporting - all operating from 2.7 V to 5.5 V supply with thermal protection and short-circuit detection.
Key Specifications

Pinout & Package
DRV2625YFFT uses a 9-pin DSBGA package (1.498 mm × 1.361 mm, 0.4 mm pitch) optimized for space-constrained portable designs. The package features bottom-side solder balls and requires controlled thermal relief on PCB pads per TI SLOS879C layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | Primary 2.7–5.5 V rail; requires 0.1 µF decoupling capacitor close to pin for stable operation. |
| GND | Ground reference | Common return path for power, analog, and digital domains; must be low-impedance and thermally connected to PCB ground plane. |
| REG | 1.8 V regulator output | Provides regulated 1.8 V for external logic or level-shifting; requires 0.1 µF capacitor and supports up to 10 mA load. |
| OUT+ | Positive differential haptic output | Drives one side of LRA/ERM load; paired with OUT− to deliver bipolar drive voltage up to VDD. |
| OUT− | Negative differential haptic output | Completes differential drive path; enables zero-crossing control and reduces EMI vs single-ended drivers. |
| SDA | I²C data bidirectional line | Open-drain interface compatible with 1.8 V logic; supports standard/fast-mode I²C up to 400 kHz. |
| SCL | I²C clock input | Drives synchronous communication; internal pull-up not provided - external 2.2–10 kΩ pull-up required. |
| TRIG/INTZ | Multi-function trigger/interrupt pin | Configurable as pulse-trigger input (active-high), enable signal, or open-drain interrupt output reporting fault/status. |
| NRST | Hardware reset/shutdown control | Pulling low forces full shutdown (180 nA); floating or tied to VDD enables normal operation with auto-standby transition. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar haptic driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV2605LRTVT | Higher 2.5 mA quiescent current; no REG pin; lacks automatic resonance reporting and TouchSense® license. | Targeted at cost-sensitive ERM-only designs without closed-loop LRA support or advanced diagnostics. | Select when LRA resonance tracking and ultra-low standby power are not required, and BOM cost is prioritized over feature set. |
| MAX20303EWL+T | Integrated PMIC + haptic driver; 3.5 µA standby; no built-in waveform library; supports only ERM. | Used in space-constrained IoT sensors requiring power management co-location, not pure haptic optimization. | Choose when combining haptics with buck/boost regulation and fuel gauging is needed - not for high-fidelity LRA systems. |

FAQ
What is the primary function of the DRV2625YFFT in a haptic system?
The DRV2625YFFT serves as a closed-loop haptic driver that autonomously manages LRA and ERM actuator performance through real-time back-EMF monitoring, automatic resonance tracking, overdrive, and braking. Unlike open-loop drivers, it relieves the host MCU from waveform timing and amplitude compensation - ensuring consistent tactile output across varying battery voltage, temperature, and actuator tolerances. The DRV2625YFFT executes this using its integrated TouchSense® 2200 library and 1 kB waveform sequencer.
How does the DRV2625YFFT achieve ultra-low-power operation?
The DRV2625YFFT achieves ultra-low-power operation via multiple hardware-enforced states: shutdown mode draws only 105–180 nA when NRST is pulled low; standby mode consumes just 1.55 µA at 3.6 V with automatic transition after inactivity; and intelligent power preservation adjusts drive strength dynamically as VDD declines from 5.5 V to 2.7 V. These features collectively extend battery life in wearables and mobile devices without sacrificing haptic fidelity - a capability confirmed in TI's SLOS879C characterization data.
Can the DRV2625YFFT drive both LRA and ERM actuators interchangeably?
Yes, the DRV2625YFFT supports both LRA and ERM actuators via software-configurable LRA_ERM bit. In LRA mode, it activates closed-loop resonance tracking, waveform shape selection (sine/square), and real-time frequency reporting. In ERM mode, it applies automatic overdrive and braking based on acceleration feedback - eliminating need for custom waveforms per motor. The DRV2625YFFT validates actuator presence and impedance before initialization, ensuring safe operation regardless of type.
What role does the REG pin serve on the DRV2625YFFT?
The REG pin on the DRV2625YFFT outputs a regulated 1.8 V supply derived from VDD, capable of sourcing up to 10 mA. It is intended to power external 1.8 V logic, level shifters, or sensor interfaces - reducing need for a separate LDO in compact designs. A 0.1 µF ceramic capacitor is mandatory at the REG pin per TI SLOS879C layout guidance to ensure stability and transient response. This feature simplifies power architecture in space-constrained applications like earbuds and smartwatches where the DRV2625YFFT is commonly deployed.
Does the DRV2625YFFT require external components for basic operation?
Yes, the DRV2625YFFT requires two mandatory external capacitors: a 0.1 µF ceramic capacitor on VDD (close to the pin) and another 0.1 µF on REG for regulator stability. No external resistors or inductors are needed for core haptic operation. The I²C interface requires external pull-up resistors (2.2–10 kΩ) on SDA/SCL. All other functions - including diagnostics, resonance tracking, and waveform playback - are fully self-contained within the DRV2625YFFT die and its internal ROM/RAM resources.
