The device is the high voltage H-bridge, single chip LRA haptic driver, with LRA resonant frequency detect and tracking, with an integrated boost converter and integrated waveform memory, supporting real time playback and hardware pin trigger playback. Maximum drive voltage is up to 10.5V and a typical startup time of 1.2ms makes the device an ideal haptic driver for fast responses.
The device supports software controlled LRA resonant frequency(F0)detect, it can detect the actual F0 after LRA delivered to customer or the actual F0 after LRA mounted in the mobile.
The device supports LRA resonant frequency tracking based on LRA BEMF. It supports automatically tracks and generates the LRA resonant frequency.
The device supports LRA fault diagnostic based on resistance measurement.
The device supports real time playback for long waveform play. Software trigger and hardware trigger are supported for different applications.
The device integrates a high-efficiency boost converter as the H-Bridge driver supply rail. The output voltage, maximum current limit and maximum boost current are configurable.
The device features configurable automatically switch to standby mode. This can less quiescent power consumption. Dedicated interrupt output pin can detect real time FIFO status and the error status of the chip.
The device offers short circuit protection, over-temperature protection, under-voltage protection to protect the device.
The device features general settings are communicated via an I2C-bus interface and its I2Caddress is configurable.
The device is available in a FCQFN3mm x 2mm x 0.55mm-20Lpackage.
