DRV2604LYZFR

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.

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.

- Pin count: 16 pins (VSSOP-16 package, DRV2604LYZFR).
- Function: One-channel inductive-load driver (solenoid/vibration motor) with PWM/current-regulated drive. Provides an H-bridge to drive an inductive load, programmable peak current, soft-start/stop, and protections (short-circuit/overcurrent/thermal, etc.) with standard control inputs (EN/PWM/IN).

- Manufacturer: Texas Instruments (TI).
- What kind of company: Texas Instruments is an American multinational semiconductor company that designs and manufactures analog and embedded processing ICs used across automotive, industrial, consumer, and other markets. It is one of the world’s largest semiconductor makers.
