DRV2603 Haptic Drive With Auto-Resonance Detection for Linear Resonance Actuators
(LRA)
1 Features 3 Description
The DRV2603 is a haptic driver designed specifically

Resonance Actuator (LRA) and Eccentric Rotating
– ERM (Eccentric Rotating Mass)
Mass (ERM) haptic elements. The DRV2603 is
designed for low latency, high efficiency, and more

feedback in the portable market.
– Automatic Drive Commutation
LRA actuators typically have a narrow frequency

response. This frequency window is typically ±2.5 Hz
wide or less, so driving an LRA actuator presents a
• Constant Vibration Strength Over Supply
challenge. The DRV2603 solves this problem by
• Automatic Input Level Translation
employing auto resonance tracking, which
• 0% to 100% Duty Cycle Control Range
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
• Differential Drive from Single-Ended Input
kHz) will automatically produce the correct resonant
• Wide Supply Voltage Range of 2.5 V to 5.2 V
output frequency. As an additional benefit, the

DRV2603 implements an automatic braking algorithm
to prevent LRA ringing at the end of waveforms,
• 1.8-V Compatible, 5-V Tolerant Digital Pins
leaving the user with a crisp haptic sensation.
• Available in a 2 mm × 2 mm × 0.75 mm Leadless
For both ERM and LRA actuators, the automatic input

output voltage does not change. The DRV2603 also
• Watches and Wearable Technology
has supply correction that ensures no supply
