Figure 47 – LRA Drive Signal Example
The carrier frequency of VMOUT_Freq is defined as following:
VMOUT_Freq(Hz) = (MIN_Freq / HAPTRANGE)
(PWM mode)
OR
VMOUT_Freq(Hz) = (MIN_Freq / HAPTRANGE) / (HAPTTIMER +1)
(I2C mode)
If AmplitudeCode is within HAPTSQUELCH range (for more than 512/VMOUT_Freq):
VMOUT_Envelope = 0V
Else:
VMOUT_Envelope(V) = (AmplitudeCode / 127) x 1.135 * HAPTGAIN
AmplitudeCode (signed) is defined differently depending on the mode selected (PWM or I2C), see below.
Please note that whatever setting, VMOUT is physically limited to [MVDD;-MVDD], ie saturation effect.
6.3.2
PWM Mode
PWM mode is selected when HAPTMODE = 0.
In this mode, AmplitudeCode is extracted/updated at each MIN period from MIN_DutyCycle:
MIN_DutyCycle
≈ 0% => AmplitudeCode = -127
…
MIN_DutyCycle = 49.6% => AmplitudeCode = -1
MIN_DutyCycle = 50% => AmplitudeCode = 0
MIN_DutyCycle = 50.4% => AmplitudeCode = +1
…
MIN_DutyCycle
≈ 100% => AmplitudeCode = +127
6.3.3
I2C Mode
I2C mode is selected when HAPTMODE = 1.
In this mode, AmplitudeCode = HAPTAMP (signed, internally sampled at MIN_Freq). MIN is still used to extract
VMOUT carrier frequency.
6.4
Short-Circuit Protection
The haptics interface integrates a short-circuit protection circuit which detects when MIDD is abnormally high i.e.
above ISHORT.
Under a short-circuit event (HAPTSHORTSTAT=1) the haptics block will stop operation
(MOUTN & MOUTP grounded). When the short-circuit is removed the haptics operations will resume normally.
