3 Description
The DRV2603 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 ±2.5 Hz
wide or less, so driving an LRA actuator presents a
challenge. The DRV2603 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 (10 kHz to 250
kHz) will automatically produce the correct resonant
output frequency. As an additional benefit, the
DRV2603 implements an automatic braking algorithm
to prevent LRA ringing at the end of waveforms,
leaving the user with a crisp haptic sensation.
For both ERM and LRA actuators, the automatic input
level translation solves issues with low voltage PWM
sources without adding additional external
components, so if the digital I/O levels vary, the
output voltage does not change. The DRV2603 also
has supply correction that ensures no supply
regulation is required for constant vibration strength,
allowing an efficient, direct-battery connection.
