DRV2605LTDGSRQ1

The DRV2605LTDGSRQ1 is a TI haptic motor driver (DRV2605L) in a RoHS-compliant package. It is used to drive vibration motors (ERM/LRA) in mobile/wearable devices, providing built‑in waveform sequences and programmable control via a serial interface.
Key points:
- Drives high/low side of a vibration motor (H-bridge)
- Built-in haptic waveform sequencer with pre-programmed effects
- Programmable current and drive modes
- Serial control interface for MCU integration (select effects, triggers, amplitude)
- Protections (short-circuit, overcurrent, thermal)
- Suitable for compact devices, low power operation
Usage: connect power, GND, and the motor; configure effects/sequences and amplitude via registers; trigger haptic events as needed.
For exact electrical specs, packaging, and feature set, refer to the TI DRV2605L datasheet and product page.

Direct equivalents are other TI DRV2605L variants in different packages (same silicon, different package code). There is no guaranteed one-to-one cross-vendor equivalent; for non‑TI matches, specify target vendors (e.g., Analog Devices, ST, NXP) for closest alternatives.
