FAH4840 - Haptic Driver

General Description

The FAH4840 is a high-performance amplifier for mobile phones and other hand-held devices.

The haptic driver takes a single-ended PWM input signal to control a Linear Resonant Actuator (LRA).

Key Features

  • Direct Drive of LRA (Linear Resonant Actuator) External PWM Input (10 kHz to 250 kHz) with Divider Internal Motor Enable / Disable Input Auto Resonant Tracking LDO Provides Stable Haptic Effect with Battery Depletion Low Shutdown Current: < 5 nA Fast Wake-Up Time Nearly Rail-to-Rail Output Swing Thermal Shutdown, Over-Current Shutdown Register-Based Control by I C Immersion TouchSense® 3000 Certified Package: 8- Lead MicroPa.
