Key Features

■ LRA or ERM drive capability

■ Automatic LRA resonant frequency tracking

■ Wideband LRA support

■ I2C and PWM input streaming

■ Low latency (0.75 ms) I2C/GPI wake-up

from low power consumption IDLE state,

IQ = 0.36 μA

■ Ultra-low latency (0.15 ms) wake-up from

STANDBY state, IQ = 0.8 mA

■ GPI pin for triggering of up to two independent

haptic sequences

■ On-board Waveform Memory with amplitude,

time, and frequency control

■ Active Acceleration and Rapid Stop

technology for high-fidelity haptic feedback

■ Actuator diagnostics and fault handling

■ Up to four I2C addresses via two address pins

■ No software requirements with embedded

operation

■ Differential PWM output drive

■ Current driven system to deliver constant

actuator power

■ Configurable EMI suppression

■ Ultra-low power consumption, IQ = 0.36 μA,

with state retention in IDLE state

■ Supply monitoring, reporting, and automatic

output limiting

■ Open- and closed-loop modes

■ Custom wave drive support

■ Small solution footprint requiring only one

decoupling capacitor in both WLCSP and QFN
