Product details
Overview
DRV2665RGPT from Texas Instruments is a piezo haptic driver IC with integrated 105-V boost converter, fully differential high-voltage amplifier, and Immersion TS5000-compliant digital front end. It delivers up to 200 VPP differential output at 300 Hz into 100 nF loads, supports I²C-controlled waveform playback via 100-byte FIFO, and operates from 3.3–5.5 V supply. It enables fast-response tactile feedback in compact portable devices.
For engineers reviewing the DRV2665RGPT datasheet, DRV2665RGPT pinout, DRV2665RGPT application, or DRV2665RGPT equivalent, key selection considerations include its 2-ms startup time, programmable boost voltage (15–105 V), differential piezo drive capability, 1.8-V-tolerant I²C interface, and thermal/brownout/overcurrent protection features.
Technical Context
The DRV2665RGPT integrates a digitally controlled 105-V boost converter with adjustable current limit (via REXT), a fully differential Class-AB amplifier with four programmable gain settings (28.8–40.7 dB), and an I²C-compatible 8-kHz digital playback engine with 100-byte FIFO. Its digital front end relieves host processor load by handling waveform sequencing and DAC conversion internally.
It supports dual input paths: real-time I²C FIFO streaming for precise haptic timing, and analog differential inputs (IN+/IN−) for direct signal injection. Startup is initiated by FIFO write or EN_OVERRIDE assertion, with full boost/amplifier enable completed within 2 ms-critical for sub-30-ms total system latency in touch feedback applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar piezo haptic driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV2667RGPT | Includes integrated LRA driver alongside piezo support; higher quiescent current (24 mA vs 175 µA in digital mode); same QFN-20 package | Targeted at dual-actuator systems requiring both piezo and LRA support; not optimized for piezo-only designs | Select DRV2667RGPT only if LRA co-driving is required; otherwise DRV2665RGPT offers lower power and simpler design |
| MAX20303EWL+ | Integrated PMIC + haptic driver; 40-V max piezo output; no internal boost; requires external HV supply; WLP-36 package | Designed for ultra-low-power wearables with tight space constraints; lacks 100-VPP capability and TS5000 compliance | Choose MAX20303EWL+ for battery-limited wearables needing multi-rail power management; DRV2665RGPT preferred for full-fidelity piezo performance |
Compared with DRV2667RGPT and MAX20303EWL+, the DRV2665RGPT delivers superior piezo-specific performance-higher voltage drive (200 VPP), faster startup (2 ms), and dedicated TS5000 firmware compatibility-making it optimal for premium mobile and industrial haptics where fidelity and responsiveness are prioritized over multi-actuator flexibility or ultra-low quiescent current.

FAQ
What is the maximum piezo load capacitance DRV2665RGPT can drive at 200 VPP?
The DRV2665RGPT can drive up to 100 nF at 200 VPP and 300 Hz, as specified in the datasheet under recommended operating conditions. This capability is enabled by its integrated 105-V boost converter and fully differential amplifier architecture. For larger capacitive loads, output voltage must be reduced-for example, 680 nF at 50 VPP. Designers should verify load matching using the CL vs VOUT curves in Section 6.3.
Does DRV2665RGPT support both digital and analog input modes simultaneously?
No, the DRV2665RGPT does not support simultaneous digital and analog input modes. It operates in either FIFO-driven digital mode (via I²C writes to address 0x0B) or analog playback mode (enabled by setting the INPUT_MUX bit), but not both concurrently. Mode selection is register-controlled and mutually exclusive to ensure signal path integrity and prevent interference between the digital engine and analog front end.
How is the boost voltage programmed on DRV2665RGPT?
The boost voltage on DRV2665RGPT is programmed using an external resistive divider connected between BST and GND, with the FB pin tied to the midpoint. The output voltage follows VBST = 1.32 V × (1 + R1/R2), where R1 connects to BST and R2 to GND. TI recommends R1 + R2 > 400 kΩ to minimize leakage current. The resulting VBST must exceed the peak output voltage by ≥5 V to ensure amplifier headroom and avoid clipping.
What protection features are built into DRV2665RGPT?
The DRV2665RGPT integrates thermal shutdown (trips at 150°C junction), overcurrent limiting (programmed via REXT), and brownout protection (resets device if REG falls below 0.84 V). It also includes short-circuit protection on the high-voltage outputs and pop-less shutdown sequencing to eliminate audible transients. These features eliminate the need for external supervision circuitry and enhance system reliability in demanding haptic applications.
Is DRV2665RGPT pin-compatible with other members of the DRV26xx family?
No, DRV2665RGPT is not pin-compatible with other DRV26xx devices such as DRV2605 or DRV2667. While all share the RGP (QFN-20) package footprint, pin functions differ significantly-especially for BST, PVDD, OUT+, OUT−, and REXT assignments. Layout reuse is not possible without verification against each device's specific pin configuration table; the DRV2665RGPT pinout is unique to its integrated boost and differential amplifier architecture.
