TEXAS INSTRUMENTS DRV2603RUNT 芯片, 触觉/震动驱动器, LRA/ERM, 10QFN
The is a Haptic Driver designed specifically to solve common obstacles in driving both Linear Resonance Actuator LRA and Eccentric Rotating Mass ERM haptic elements. The DRV2603 is designed for low latency, high efficiency and more drive strength for actuators commonly used for tactile feedback in the portable market. LRA actuators typically have a narrow frequency band over which they have an adequate haptic response. This frequency window is typically ±2.5Hz wide or less, so driving an LRA actuator presents a challenge. The driver solves this problem by employing auto resonance tracking, which automatically detects and tracks the LRA resonant frequency in real time. This means that any input PWM frequency within the input range will automatically produce the correct resonant output frequency. As an additional benefit, the driver implements an automatic braking algorithm to prevent LRA ringing at the end of waveforms, leaving the user with a crisp haptic sensation.
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
