Product details
Overview
DRV2604LYZFR from Texas Instruments is a 2-V to 5.2-V haptic driver IC for linear resonance actuators (LRA) and eccentric rotating mass (ERM) motors, featuring integrated RAM, I²C-controlled playback engine, smart-loop closed-loop control with automatic resonance tracking (LRA), overdrive/braking, and back-EMF detection. It delivers consistent tactile feedback in mobile phones and tablets.
For engineers reviewing the DRV2604LYZFR datasheet, DRV2604LYZFR pinout, DRV2604LYZFR application, or DRV2604LYZFR equivalent, key selection criteria include LRA/ERM dual-mode support, 9-pin DSBGA package compatibility, 1.8-V I²C interface tolerance, internal waveform memory capacity (>100 waveforms), and real-time playback capability via I²C.
Technical Context
The DRV2604LYZFR implements a patent-pending smart-loop architecture combining real-time back-EMF sensing, auto-resonance tracking for LRAs (125–300 Hz), and feedback-optimized ERM drive. Its trinary-modulated differential output stage enables efficient switching drive with automatic overdrive boost and brake stabilization.
It supports three operational modes: RAM-based waveform playback (I²C or hardware trigger), real-time playback (RTP) via I²C, and open-loop PWM/analog input. The device automatically transitions between closed-loop and open-loop operation based on valid back-EMF detection, with configurable loop gain, brake factor, and calibration timing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar haptic driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV2605L | Includes integrated boost converter (up to 110 V); supports higher-voltage LRAs; larger 16-pin VQFN package | Required for high-performance LRAs needing >5.2 V drive; not drop-in compatible due to different pinout and power architecture | Select when driving high-impedance LRAs or requiring extended voltage headroom beyond battery rail |

FAQ
What is the primary function of the DRV2604LYZFR in a haptic system?
The DRV2604LYZFR serves as a programmable haptic driver IC that provides closed-loop control for both linear resonance actuators (LRA) and eccentric rotating mass (ERM) motors. It executes automatic resonance tracking, overdrive, braking, and level calibration using back-EMF feedback. The DRV2604LYZFR integrates an I²C-controlled playback engine and >100-waveform RAM, enabling high-fidelity tactile feedback in compact mobile devices without host processor overhead.
Does the DRV2604LYZFR require external components for basic operation?
Yes, the DRV2604LYZFR requires two mandatory external capacitors: a 1-µF ceramic capacitor on VDD and a 1-µF capacitor on the REG pin. These ensure stable power delivery and proper 1.8-V I²C interface regulation. No external inductors or boost circuitry are needed, as the DRV2604LYZFR uses an efficient trinary-modulated differential output stage. All other functionality-including RAM storage, smart-loop algorithms, and diagnostics-is fully integrated within the DRV2604LYZFR die.
How does the smart-loop architecture in the DRV2604LYZFR improve LRA performance?
The smart-loop architecture in the DRV2604LYZFR improves LRA performance by continuously monitoring back-EMF to track resonant frequency in real time (125–300 Hz), automatically adjusting drive frequency to maintain peak efficiency. It enables automatic overdrive at startup and active braking at stop-reducing latency to 0.7 ms-and performs on-the-fly level calibration to compensate for actuator variance and battery droop. This eliminates manual tuning and ensures consistent tactile output across temperature, aging, and voltage conditions for the DRV2604LYZFR.
Can the DRV2604LYZFR operate in open-loop mode, and when would that be necessary?
Yes, the DRV2604LYZFR can operate in open-loop mode via its IN/TRIG pin configured for PWM or analog input, or automatically when LRA back-EMF is invalid. Open-loop mode is necessary for off-resonance LRA driving, rapid prototyping without calibration, or fallback operation during actuator fault conditions. While open-loop mode bypasses smart-loop benefits like auto-tracking and braking, the DRV2604LYZFR retains internal PWM generation and 0–100% duty-cycle control-ensuring functional haptic output even when closed-loop operation is unavailable.
What package type and footprint does the DRV2604LYZFR use, and why is it significant?
The DRV2604LYZFR uses a 9-pin DSBGA (YZF) package measuring 1.50 mm × 1.50 mm with 0.5-mm pitch. This ultra-compact chip-scale package minimizes PCB area-critical for thin smartphones and wearables-while maintaining thermal performance (θJA = 145.2 °C/W). Its solder-ball layout enables high-density routing and low-inductance connections to VDD and GND. The YZF footprint is standardized across TI's haptic portfolio, simplifying design reuse and reducing layout risk for the DRV2604LYZFR in space-constrained applications.
