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.

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

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.
