描述 Description

High Power Vibration Motor Driver

DW7914A is a high power vibration motor driver that delivers intensive vibration effects with high voltage boost converter and H-bridge driver. The real-time playback mode is a simple 8-bit register interface where the user enters a register value over I2C. The internal memory and the memory playback mode using waveform sequencer reduce the burden imposed on the host processor including offloading processing requirements such as digital streaming, latency improvement and I2C traffic reduction. DW7914A features a full shutdown and an automatic go-to-standby state to reduce power consumption. The trigger playback is possible up to three other with priority option. The automatic resonance tracking supports to maximize the vibration power efficiency and automatic braking option with optimum waveform reduces the brake time for the better tactile feedback.
