Key Features
■ LRA drive capability
■ No device programming required
■ Three GPI pins for triggering clicks and
complex patterns at two drive levels
■ Automatic LRA resonant frequency tracking
■ Ultra-low power consumption, IQ = 5 nA,
when the device is disabled
■ Low latency (0.75 ms) GPI wake-up
from low power consumption IDLE state,
IQ = 0.68 μA
■ Differential PWM output drive
■ Edge rate control for EMI suppression
■ Current driven system to deliver constant
actuator power
■ Automatic short circuit protection
■ Automatic over-temperature protection
■ Automatic under-voltage lockout protection
■ Automatic haptic playback timeout in case of
host disappearance
■ Supply monitoring and automatic output
limiting
■ Small solution footprint requiring only one
decoupling capacitor in both WLCSP and QFN
