Haptic Driver with Auto Resonance Tracking for Linear Resonance Actuators (LRA) and

Optimized Drive for Eccentric Rotating Mass Actuators (ERM)

Check for Samples: DRV2603

FEATURES

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 also

designed for low latency, has excellent efficiency, and

plenty of drive strength for actuators commonly used

in the portable market.

Auto Resonance Tracking for LRA

–

No Frequency Calibration Required

Automatic Drive Commutation

Automatic Braking Algorithm

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

Wide Input PWM Frequency Range

•

Constant Vibration Strength Over Supply

Automatic Input Level Translation

0% to 100% Duty Cycle Control Range

Fast Start Up Time

employing

auto

resonance

tracking,

which

automatically detects and tracks the optimum

commutation frequency. 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 optimal braking algorithm to

stop the LRA from ringing out, leaving the user with a

crisp haptic sensation.

Differential Drive from Single-Ended Input

Wide Supply Voltage Range of 2.5 V to 5.2 V

1.8 V Compatible, 5 V Tolerant Digital Pins

Available in a 2 mm × 2 mm × 0.75 mm

leadless QFN package (RUN)

For both ERM and LRA actuators, the DRV2603

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.
