5 functional Description
5.1 supply section
The device is powered by two supply voltages, VBAT_HV and VDD. VBAT_HV is the battery voltage behind a reverse
protection diode, and VDD is the digital 5.0V supply, also needed for several analog functions. Both voltages are
monitored internally.
From the 5.0V VDD supply input, a 3.3V supply voltage is generated by an internal linear voltage regulator. The pin
VDDA3 represents the output of the regulator and at the same the supply for the analog part of the IC. An exter-
nal buffer capacitor CVDDA3 shall be connected to VDDA3. The pin VDDD3 represents the supply for the digital
part of the IC and shall be connected to VDDA3 by an external decoupling network, consisting of a resistor RF and
a second buffer capacitor CVDDD3.
For all outputs in motor control mode, in case of an overvoltage or undervoltage on VBAT_HV, all outputs are
switched into brake mode (low side drivers on). Ripple detection is still performed as long as VDD is present. All
outputs, which are driving other loads than motors, are only switched off in case of overvoltage.
When VDD drops below the low voltage threshold all outputs are switched to tristate (high impedance) mode to
avoid destruction in case of a short circuit. The internal charge pump will be turned off, and the device draws only
standby current IBAT,STBY from the VBAT_HV supply.
When VDD is present, a standby mode for both VBAT_HV and VDD can be activated via an SPI telegram (see chap-
ter 5.2.17).
VBAT_HV and VDD may be turned on and off in any sequence.
