RM101

High Definition Digital Haptic Driver IC

• Description

  The RM101 is a high definition haptic driverIC with integrated digital front end, digital-to-analog converter, anddifferential output driver amp. It receives digital haptic data via I2C bus. Then converts the data into highfidelity analog signal using DAC, and drives actuator with high current withonly 0.4 ms of turn-on time. Current limit and thermal overload protectionprevent the device from being damaged when IC is overloaded.
