Product details
Overview
DRV2604YZFR from Texas Instruments is a haptic driver IC designed for closed-loop control of both Linear Resonance Actuators (LRA) and Eccentric Rotating Mass (ERM) motors via I²C or hardware trigger. It integrates 2 kB RAM for >100 waveforms, features smart-loop architecture with automatic resonance tracking (125–300 Hz), overdrive/braking, and back-EMF-based diagnostics. Used in mobile phones and tablets for precise tactile feedback.
For engineers reviewing the DRV2604YZFR datasheet, DRV2604YZFR pinout, DRV2604YZFR application, or DRV2604YZFR equivalent, key selection criteria include LRA/ERM dual-mode support, 9-ball DSBGA package (1.5 mm × 1.5 mm), trinary-modulated output efficiency, 2.5–5.5 V supply range, and Immersion TouchSense® 3000 compatibility.
Technical Context
The DRV2604YZFR implements a proprietary smart-loop architecture using real-time back-EMF detection to enable automatic resonance tracking for LRAs and feedback-optimized drive for ERMs. It supports three operational modes: internal RAM playback, real-time I²C streaming (RTP), and multi-mode IN/TRIG input (PWM/analog/hardware trigger).
Its trinary-modulated output stage delivers higher efficiency than linear drivers, while integrated 1.8-V REG output powers external logic. The device achieves <0.7 ms start-up latency and maintains constant acceleration across supply voltage variation, enabled by closed-loop gain control and auto-calibration of actuator impedance and back-EMF magnitude.

Equivalent & Alternatives
The following parts are listed as comparable options for similar haptic driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV2605LRTVT | Includes integrated boost converter (up to 22 V); supports higher-voltage LRAs; larger 16-pin QFN package | Required for LRAs needing >5.5 V drive; not suitable for space-constrained designs where DRV2604YZFR's 1.5 mm × 1.5 mm DSBGA is critical | Choose DRV2605LRTVT when driving high-impedance LRAs or when system lacks dedicated high-voltage rail. |
| MAX20303EWE+T | Integrated power management (buck, LDO, charger) + haptic driver; 24-pin WLP; no internal RAM; relies on host RTP streaming | Targets ultra-low-power wearables requiring PMIC + haptics in one die; lacks autonomous waveform storage and smart-loop calibration | Choose MAX20303EWE+T when consolidating power and haptics is prioritized over autonomous closed-loop control. |
Compared with DRV2605LRTVT and MAX20303EWE+T, the DRV2604YZFR uniquely balances ultra-small footprint, self-contained waveform memory, and full smart-loop autonomy-making it optimal for mid-tier mobile and tablet designs where board area and host processing offload are primary constraints.

FAQ
What actuator types does the DRV2604YZFR support?
The DRV2604YZFR supports both Linear Resonance Actuators (LRA) and Eccentric Rotating Mass (ERM) motors. It automatically configures its smart-loop architecture based on the selected mode via register 0x1A. For LRAs, it performs real-time resonance tracking (125–300 Hz); for ERMs, it applies feedback-optimized overdrive and braking. The DRV2604YZFR does not support solenoids or voice-coil actuators outside this dual-mode specification.
How does the DRV2604YZFR achieve consistent haptic performance across varying battery voltage?
The DRV2604YZFR maintains constant acceleration across its 2.5–5.5 V supply range using closed-loop back-EMF feedback and adaptive loop-gain control. Its smart-loop architecture continuously adjusts drive amplitude to compensate for voltage sag, ensuring identical tactile intensity whether powered by a fresh 4.2 V Li-ion cell or a depleted 3.0 V battery-without requiring host-side gain scaling.
Does the DRV2604YZFR require external components for basic operation?
Yes-the DRV2604YZFR requires two mandatory external capacitors: a 0.1-µF ceramic capacitor on VDD and a 1-µF capacitor on the REG pin. No external resistors, inductors, or op-amps are needed for standard LRA/ERM drive. All signal conditioning, waveform sequencing, and feedback control are fully integrated, minimizing BOM count and PCB area.
Can the DRV2604YZFR operate without an I²C host controller?
Yes-the DRV2604YZFR supports standalone operation via its IN/TRIG pin configured as a hardware trigger. When enabled, a rising edge on IN/TRIG initiates playback of the waveform sequence stored in RAM (registers 0x04–0x0B). This allows tactile feedback activation directly from GPIO or PMIC signals, eliminating dependency on continuous I²C communication during runtime.
What is the purpose of the REG pin on the DRV2604YZFR?
The REG pin on the DRV2604YZFR outputs a regulated 1.8-V supply derived from VDD, intended to power external 1.8-V logic such as baseband processors or companion sensors. It is not an input and cannot be used to power the DRV2604YZFR itself. A 1-µF capacitor must be placed between REG and GND to ensure stability and noise suppression, as specified in the recommended operating conditions.
