Notes
(1) No more than 100 cumulated hours in life time above
Ttsd.
(2) Communication over serial bus is operating. Motordriver
is disabled when Vbb < UV2.
(3) Pin VDD must not be used for any external supply.
(4) The RAM content will not be altered above this voltage.
(5) External resistance value seen from pin SWI or HW,
including 1kΩ series resistor.
(6) If input voltage ≤ 0.3V, then a resistor of 22 to 100Ω
must be added in series.
(7) In case 100kHz ≤ f_SCL ≤ 360kHz V_IH min = 0.7V_DD.
