Overview
Description
DRV2604LYZFR is TI’s vibration-motor driver IC used to drive ERM/LRA motors in portable devices. It integrates a motor driver with current regulation and protection features in a small RoHS-compliant package. It offers configurable haptic waveforms (built-in sequences) and can be controlled by simple signals (PWM or digital input) to set amplitude and timing. Protective functions include short-circuit/overcurrent protection, undervoltage lockout, and thermal shutdown for robust operation. Common applications are phones, wearables, and handheld gadgets needing compact, quiet, energy-efficient vibration feedback. For exact electrical specs (supply range, peak current, pinout, interface, and waveform library), consult the DRV2604 datasheet and TI packaging information for the LYZFR variant.
Features
Key features of DRV2604LYZFR:
- 4 independent haptic driver channels for ERM/LRA motors
- Built-in waveform engine with selectable patterns; programmable amplitude and duration per channel
- Serial control interface (I2C-/SPI-like) for pattern selection and parameter control
- Adjustable drive current and ramp/soft-start for quiet, smooth operation
- Protective circuitry: undervoltage lockout, overcurrent/short-circuit protection, thermal shutdown
- Suitable for battery-powered apps; wide supply range (approx. 2.7–5.5 V)
- Low quiescent current and compact package for space-constrained devices
- RoHS-compliant packaging (LYZFR variant)
Note: exact interface wording and current specs may vary by revision; refer to datasheet for precise electrical characteristics.
