Product details
Overview
DA7283-01FV2 from Renesas Electronics is an ultra-low-power linear resonant actuator (LRA) haptic driver with automatic closed-loop resonant frequency tracking, 0.75 ms GPI wake-up latency, and software-free operation. It delivers differential PWM drive at 187.5 kHz, supports three GPI-triggered haptic effects at two drive levels, and consumes only 5 nA in OFF mode. It is deployed in wearables and security-sensitive industrial interfaces where minimal firmware footprint and consistent tactile feedback are critical.
For engineers reviewing the DA7283-01FV2 datasheet, DA7283-01FV2 pinout, DA7283-01FV2 application, or DA7283-01FV2 equivalent, key selection considerations include its GPI-only trigger architecture (no I2C), 150–250 Hz auto-tracking range, 5 nA OFF-state current, and WLCSP/QFN package options - all essential for battery-constrained, host-less haptic systems.
Technical Context
The DA7283-01FV2 implements a current-regulated, H-bridge differential PWM output architecture operating at 187.5 kHz, enabling constant-force LRA drive independent of back-EMF amplitude. Its closed-loop BEMF sensing continuously tracks resonant frequency between 150 Hz and 250 Hz with ±0.5 Hz accuracy during playback.
Three digital input GPI pins (GPI_0, GPI_1, GPI_2) provide edge-triggered, low-latency (0.75 ms) wake-up from IDLE state (0.68 µA), with automatic return to ultra-low-power IDLE after playback. The VDDIO/EN pin enables full device reset and 5 nA OFF-state consumption, while ERC-controlled edge rates suppress EMI without external RC filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| OFF-state current | 5 nA - enables multi-year battery life in always-off standby devices like remote controls and disposable sensors. |
| IDLE-state current | 0.68 µA - sustains ready-to-wake operation for >1 year on a CR2032 coin cell in wearables. |
| GPI wake-up latency | 0.75 ms - ensures perceptually immediate tactile response to button press or NFC interrupt. |
| LRA frequency tracking range | 150–250 Hz - covers full production spread and thermal drift of common LRAs without calibration. |
| Tracking accuracy | ±0.5 Hz during playback - maintains peak acceleration within 5% across temperature and aging. |
| PWM output frequency | 187.5 kHz - enables efficient switching with minimal audible noise and compact passive filtering. |
| Short-circuit protection threshold | 500 mA typical - safeguards against OUTP/OUTN shorts to GND, VDD, or each other without latch-up. |
| Supply voltage range (VDD) | 2.8–5.5 V - supports direct Li-ion battery (3.0–4.2 V) or regulated 3.3 V/5 V rails without boost converter. |
Pinout & Package
DA7283-01FV2 is available in both wafer-level chip-scale package (WLCSP) and quad flat no-leads (QFN) variants. The -01FV2 suffix corresponds to the 16-pin WLCSP package (2.13 mm × 1.73 mm, 0.4 mm pitch), per Renesas ordering information (R15DS0040EE0320 Rev.3.20, Table 14).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GPI_0 / GPI_1 / GPI_2 | Digital input trigger | Falling-edge activated; initiates preconfigured haptic effect at one of two drive levels without host intervention. |
| OUTP / OUTN | Differential haptic drive outputs | Current-regulated H-bridge outputs delivering 230 mA max; enable 2× voltage swing vs single-ended drive. |
| VDDIO/EN | Digital supply & enable control | Active-high enable; 0 V forces full reset and 5 nA OFF state; ties to system VDDIO (1.35–5.5 V). |
| VDD | Haptic power supply | Primary power rail (2.8–5.5 V); decoupled to GND_1; powers H-bridge and internal regulation loop. |
| GND_1–GND_5 | Ground terminals | Five dedicated ground pins minimize impedance in high-current haptic drive path and improve EMI immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Software-free LRA drive | No I2C/SPI interface or firmware required - playback fully controlled by GPI timing and edge polarity. |
| Automatic resonant frequency tracking | Real-time BEMF sensing + PID control locks to LRA resonance (150–250 Hz) without actuator parameter input. |
| Differential PWM drive | H-bridge architecture doubles effective voltage swing across LRA, increasing mechanical output by ~3× vs voltage-driven solutions. |
| Edge rate control (ERC) | 100 mV/ns slew rate on OUTP/OUTN eliminates need for external RC filters, reducing BOM cost and PCB area. |
| Host-loss resilience | 60-second automatic playback timeout prevents battery drain if host crashes mid-sequence - critical for unattended devices. |
| Multi-level protection | Integrated short-circuit, over-temperature (125 °C), under-voltage lockout (2.8 V), and over-impedance detection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LRA haptic driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DA7282-01FV2 | Includes I2C interface and supports programmable waveforms; lacks VDDIO/EN pin for true 5 nA OFF state (OFF current not specified). | Required when host-controlled dynamic waveform loading or multi-actuator synchronization is needed. | Select DA7282-01FV2 only if I2C configurability outweighs the 5 nA OFF-state advantage of DA7283-01FV2. |
| TI DRV2625YZFT | Requires I2C initialization and LRA characterization data; offers library-based waveform engine but no GPI-only mode. | Suitable for smartphones with full OS driver stacks; unsuitable for host-less or ultra-low-firmware systems. | Choose DRV2625YZFT only when leveraging TI's haptic library and host CPU resources is feasible - not for standalone operation. |
Compared with DA7282-01FV2 and DRV2625YZFT, DA7283-01FV2 uniquely delivers guaranteed 5 nA OFF current, GPI-only wake-up, and zero-host firmware dependency - making it the sole option for truly autonomous, multi-year battery haptic nodes.

FAQ
Does DA7283-01FV2 require I2C programming to operate?
No. DA7283-01FV2 is explicitly designed for software-free operation: all haptic playback is initiated and controlled solely by falling-edge triggers on GPI_0, GPI_1, or GPI_2. Unlike DA7280/DA7281/DA7282, the DA7283-01FV2 omits I2C entirely - no register writes, no actuator characterization, and no host firmware dependency are needed for basic or complex pattern playback.
What is the function of the VDDIO/EN pin on DA7283-01FV2?
The VDDIO/EN pin on DA7283-01FV2 serves dual roles: it supplies digital I/O voltage (1.35–5.5 V) and acts as an active-high hardware enable. When pulled to 0 V, the device enters OFF state with 5 nA quiescent current and full internal reset. When asserted high, it powers the GPI inputs and enables IDLE/PLAYBACK states - eliminating need for software shutdown sequences.
Can DA7283-01FV2 drive any LRA, or are there specific compatibility requirements?
DA7283-01FV2 supports LRAs with nominal DC impedance of 8–25 Ω, inductance of 25–1000 µH, and resonant frequency of 160–240 Hz. Operation outside these ranges is not guaranteed; Renesas explicitly recommends using I2C-programmable DA7280/DA7281/DA7282 for out-of-spec actuators or advanced tuning. The DA7283-01FV2's auto-tracking is optimized for this defined LRA window.
How does DA7283-01FV2 achieve consistent haptic output across temperature and aging?
DA7283-01FV2 achieves consistency via real-time closed-loop BEMF sensing and PID-based resonant frequency tracking (150–250 Hz range, ±0.5 Hz accuracy). This dynamically adjusts drive frequency to match the LRA's instantaneous mechanical resonance - compensating for thermal drift, mechanical coupling changes, and aging-induced shifts that would otherwise degrade acceleration output by >50% in fixed-frequency drivers.
What protection features are integrated into DA7283-01FV2?
DA7283-01FV2 integrates five autonomous protections: (1) short-circuit detection (500 mA threshold) forcing H-bridge into high-Z state; (2) over-temperature shutdown at 125 °C; (3) under-voltage lockout below 2.8 V; (4) 60-second playback timeout to prevent battery drain during host failure; and (5) over-/under-impedance detection (4 Ω / 50 Ω thresholds) halting drive if LRA disconnects or degrades.
